-Install
-    How to install HTML Purifier
-
-HTML Purifier is designed to run out of the box, so actually using the
-library is extremely easy.  (Although... if you were looking for a
-step-by-step installation GUI, you've downloaded the wrong software!)
-
-While the impatient can get going immediately with some of the sample
-code at the bottom of this library, it's well worth reading this entire
-document--most of the other documentation assumes that you are familiar
-with these contents.
-
-
----------------------------------------------------------------------------
-1.  Compatibility
-
-HTML Purifier is PHP 5 and PHP 7, and is actively tested from PHP 5.3
-and up. It has no core dependencies with other libraries.
-
-These optional extensions can enhance the capabilities of HTML Purifier:
-
-    * iconv  : Converts text to and from non-UTF-8 encodings
-    * bcmath : Used for unit conversion and imagecrash protection
-    * tidy   : Used for pretty-printing HTML
-
-These optional libraries can enhance the capabilities of HTML Purifier:
-
-    * CSSTidy : Clean CSS stylesheets using %Core.ExtractStyleBlocks
-        Note: You should use the modernized fork of CSSTidy available
-        at https://github.com/Cerdic/CSSTidy
-    * Net_IDNA2 (PEAR) : IRI support using %Core.EnableIDNA
-        Note: This is not necessary for PHP 5.3 or later
-
----------------------------------------------------------------------------
-2.  Reconnaissance
-
-A big plus of HTML Purifier is its inerrant support of standards, so
-your web-pages should be standards-compliant.  (They should also use
-semantic markup, but that's another issue altogether, one HTML Purifier
-cannot fix without reading your mind.)
-
-HTML Purifier can process these doctypes:
-
-* XHTML 1.0 Transitional (default)
-* XHTML 1.0 Strict
-* HTML 4.01 Transitional
-* HTML 4.01 Strict
-* XHTML 1.1
-
-...and these character encodings:
-
-* UTF-8 (default)
-* Any encoding iconv supports (with crippled internationalization support)
-
-These defaults reflect what my choices would be if I were authoring an
-HTML document, however, what you choose depends on the nature of your
-codebase.  If you don't know what doctype you are using, you can determine
-the doctype from this identifier at the top of your source code:
-
-    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
-        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
-
-...and the character encoding from this code:
-
-    <meta http-equiv="Content-type" content="text/html;charset=ENCODING">
-
-If the character encoding declaration is missing, STOP NOW, and
-read 'docs/enduser-utf8.html' (web accessible at
-http://htmlpurifier.org/docs/enduser-utf8.html).  In fact, even if it is
-present, read this document anyway, as many websites specify their
-document's character encoding incorrectly.
-
-
----------------------------------------------------------------------------
-3.  Including the library
-
-The procedure is quite simple:
-
-    require_once '/path/to/library/HTMLPurifier.auto.php';
-
-This will setup an autoloader, so the library's files are only included
-when you use them.
-
-Only the contents in the library/ folder are necessary, so you can remove
-everything else when using HTML Purifier in a production environment.
-
-If you installed HTML Purifier via PEAR, all you need to do is:
-
-    require_once 'HTMLPurifier.auto.php';
-
-Please note that the usual PEAR practice of including just the classes you
-want will not work with HTML Purifier's autoloading scheme.
-
-Advanced users, read on; other users can skip to section 4.
-
-Autoload compatibility
-----------------------
-
-    HTML Purifier attempts to be as smart as possible when registering an
-    autoloader, but there are some cases where you will need to change
-    your own code to accomodate HTML Purifier. These are those cases:
-
-    AN __autoload FUNCTION IS DECLARED AFTER OUR AUTOLOADER IS REGISTERED
-        spl_autoload_register() has the curious behavior of disabling
-        the existing __autoload() handler. Users need to explicitly
-        spl_autoload_register('__autoload'). Because we use SPL when it
-        is available, __autoload() will ALWAYS be disabled. If __autoload()
-        is declared before HTML Purifier is loaded, this is not a problem:
-        HTML Purifier will register the function for you. But if it is
-        declared afterwards, it will mysteriously not work. This
-        snippet of code (after your autoloader is defined) will fix it:
-
-            spl_autoload_register('__autoload')
-
-
-For better performance
-----------------------
-
-    Opcode caches, which greatly speed up PHP initialization for scripts
-    with large amounts of code (HTML Purifier included), don't like
-    autoloaders. We offer an include file that includes all of HTML Purifier's
-    files in one go in an opcode cache friendly manner:
-
-        // If /path/to/library isn't already in your include path, uncomment
-        // the below line:
-        // require '/path/to/library/HTMLPurifier.path.php';
-
-        require 'HTMLPurifier.includes.php';
-
-    Optional components still need to be included--you'll know if you try to
-    use a feature and you get a class doesn't exists error! The autoloader
-    can be used in conjunction with this approach to catch classes that are
-    missing. Simply add this afterwards:
-
-        require 'HTMLPurifier.autoload.php';
-
-Standalone version
-------------------
-
-    HTML Purifier has a standalone distribution; you can also generate
-    a standalone file from the full version by running the script
-    maintenance/generate-standalone.php . The standalone version has the
-    benefit of having most of its code in one file, so parsing is much
-    faster and the library is easier to manage.
-
-    If HTMLPurifier.standalone.php exists in the library directory, you
-    can use it like this:
-
-        require '/path/to/HTMLPurifier.standalone.php';
-
-    This is equivalent to including HTMLPurifier.includes.php, except that
-    the contents of standalone/ will be added to your path. To override this
-    behavior, specify a new HTMLPURIFIER_PREFIX where standalone files can
-    be found (usually, this will be one directory up, the "true" library
-    directory in full distributions). Don't forget to set your path too!
-
-    The autoloader can be added to the end to ensure the classes are
-    loaded when necessary; otherwise you can manually include them.
-    To use the autoloader, use this:
-
-        require 'HTMLPurifier.autoload.php';
-
-For advanced users
-------------------
-
-    HTMLPurifier.auto.php performs a number of operations that can be done
-    individually. These are:
-
-        HTMLPurifier.path.php
-            Puts /path/to/library in the include path. For high performance,
-            this should be done in php.ini.
-
-        HTMLPurifier.autoload.php
-            Registers our autoload handler HTMLPurifier_Bootstrap::autoload($class).
-
-    You can do these operations by yourself, if you like.
-
-
----------------------------------------------------------------------------
-4. Configuration
-
-HTML Purifier is designed to run out-of-the-box, but occasionally HTML
-Purifier needs to be told what to do.  If you answer no to any of these
-questions, read on; otherwise, you can skip to the next section (or, if you're
-into configuring things just for the heck of it, skip to 4.3).
-
-* Am I using UTF-8?
-* Am I using XHTML 1.0 Transitional?
-
-If you answered no to any of these questions, instantiate a configuration
-object and read on:
-
-    $config = HTMLPurifier_Config::createDefault();
-
-
-4.1. Setting a different character encoding
-
-You really shouldn't use any other encoding except UTF-8, especially if you
-plan to support multilingual websites (read section three for more details).
-However, switching to UTF-8 is not always immediately feasible, so we can
-adapt.
-
-HTML Purifier uses iconv to support other character encodings, as such,
-any encoding that iconv supports <http://www.gnu.org/software/libiconv/>
-HTML Purifier supports with this code:
-
-    $config->set('Core.Encoding', /* put your encoding here */);
-
-An example usage for Latin-1 websites (the most common encoding for English
-websites):
-
-    $config->set('Core.Encoding', 'ISO-8859-1');
-
-Note that HTML Purifier's support for non-Unicode encodings is crippled by the
-fact that any character not supported by that encoding will be silently
-dropped, EVEN if it is ampersand escaped.  If you want to work around
-this, you are welcome to read docs/enduser-utf8.html for a fix,
-but please be cognizant of the issues the "solution" creates (for this
-reason, I do not include the solution in this document).
-
-
-4.2. Setting a different doctype
-
-For those of you using HTML 4.01 Transitional, you can disable
-XHTML output like this:
-
-    $config->set('HTML.Doctype', 'HTML 4.01 Transitional');
-
-Other supported doctypes include:
-
-    * HTML 4.01 Strict
-    * HTML 4.01 Transitional
-    * XHTML 1.0 Strict
-    * XHTML 1.0 Transitional
-    * XHTML 1.1
-
-
-4.3. Other settings
-
-There are more configuration directives which can be read about
-here: <http://htmlpurifier.org/live/configdoc/plain.html>  They're a bit boring,
-but they can help out for those of you who like to exert maximum control over
-your code.  Some of the more interesting ones are configurable at the
-demo <http://htmlpurifier.org/demo.php> and are well worth looking into
-for your own system.
-
-For example, you can fine tune allowed elements and attributes, convert
-relative URLs to absolute ones, and even autoparagraph input text! These
-are, respectively, %HTML.Allowed, %URI.MakeAbsolute and %URI.Base, and
-%AutoFormat.AutoParagraph. The %Namespace.Directive naming convention
-translates to:
-
-    $config->set('Namespace.Directive', $value);
-
-E.g.
-
-    $config->set('HTML.Allowed', 'p,b,a[href],i');
-    $config->set('URI.Base', 'http://www.example.com');
-    $config->set('URI.MakeAbsolute', true);
-    $config->set('AutoFormat.AutoParagraph', true);
-
-
----------------------------------------------------------------------------
-5. Caching
-
-HTML Purifier generates some cache files (generally one or two) to speed up
-its execution. For maximum performance, make sure that
-library/HTMLPurifier/DefinitionCache/Serializer is writeable by the webserver.
-
-If you are in the library/ folder of HTML Purifier, you can set the
-appropriate permissions using:
-
-    chmod -R 0755 HTMLPurifier/DefinitionCache/Serializer
-
-If the above command doesn't work, you may need to assign write permissions
-to group:
-
-    chmod -R 0775 HTMLPurifier/DefinitionCache/Serializer
-
-You can also chmod files via your FTP client; this option
-is usually accessible by right clicking the corresponding directory and
-then selecting "chmod" or "file permissions".
-
-Starting with 2.0.1, HTML Purifier will generate friendly error messages
-that will tell you exactly what you have to chmod the directory to, if in doubt,
-follow its advice.
-
-If you are unable or unwilling to give write permissions to the cache
-directory, you can either disable the cache (and suffer a performance
-hit):
-
-    $config->set('Core.DefinitionCache', null);
-
-Or move the cache directory somewhere else (no trailing slash):
-
-    $config->set('Cache.SerializerPath', '/home/user/absolute/path');
-
-
----------------------------------------------------------------------------
-6.   Using the code
-
-The interface is mind-numbingly simple:
-
-    $purifier = new HTMLPurifier($config);
-    $clean_html = $purifier->purify( $dirty_html );
-
-That's it!  For more examples, check out docs/examples/ (they aren't very
-different though).  Also, docs/enduser-slow.html gives advice on what to
-do if HTML Purifier is slowing down your application.
-
-
----------------------------------------------------------------------------
-7.   Quick install
-
-First, make sure library/HTMLPurifier/DefinitionCache/Serializer is
-writable by the webserver (see Section 5: Caching above for details).
-If your website is in UTF-8 and XHTML Transitional, use this code:
-
-<?php
-    require_once '/path/to/htmlpurifier/library/HTMLPurifier.auto.php';
-
-    $config = HTMLPurifier_Config::createDefault();
-    $purifier = new HTMLPurifier($config);
-    $clean_html = $purifier->purify($dirty_html);
-?>
-
-If your website is in a different encoding or doctype, use this code:
-
-<?php
-    require_once '/path/to/htmlpurifier/library/HTMLPurifier.auto.php';
-
-    $config = HTMLPurifier_Config::createDefault();
-    $config->set('Core.Encoding', 'ISO-8859-1'); // replace with your encoding
-    $config->set('HTML.Doctype', 'HTML 4.01 Transitional'); // replace with your doctype
-    $purifier = new HTMLPurifier($config);
-
-    $clean_html = $purifier->purify($dirty_html);
-?>

-Installation
-    Comment installer HTML Purifier
-
-Attention : Ce document est encodé en UTF-8, si les lettres avec des accents
-ne s'affichent pas, prenez un meilleur éditeur de texte.
-
-L'installation de HTML Purifier est très simple, parce qu'il n'a pas besoin
-de configuration. Pour les utilisateurs impatients, le code se trouve dans le
-pied de page, mais je recommande de lire le document.
-
-1.  Compatibilité
-
-HTML Purifier fonctionne avec PHP 5. PHP 5.3 est la dernière version testée.
-Il ne dépend pas d'autres librairies.
-
-Les extensions optionnelles sont iconv (généralement déjà installée) et tidy
-(répendue aussi). Si vous utilisez UTF-8 et que vous ne voulez pas l'indentation,
-vous pouvez utiliser HTML Purifier sans ces extensions.
-
-
-2.  Inclure la librairie
-
-Quand vous devez l'utilisez, incluez le :
-
-    require_once('/path/to/library/HTMLPurifier.auto.php');
-
-Ne pas l'inclure si ce n'est pas nécessaire, car HTML Purifier est lourd.
-
-HTML Purifier utilise "autoload". Si vous avez défini la fonction __autoload,
-vous devez ajouter cette fonction :
-
-    spl_autoload_register('__autoload')
-
-Plus d'informations dans le document "INSTALL".
-
-3.  Installation rapide
-
-Si votre site Web est en UTF-8 et XHTML Transitional, utilisez :
-
-<?php
-    require_once('/path/to/htmlpurifier/library/HTMLPurifier.auto.php');
-    $purificateur = new HTMLPurifier();
-    $html_propre = $purificateur->purify($html_a_purifier);
-?>
-
-Sinon, utilisez :
-
-<?php
-    require_once('/path/to/html/purifier/library/HTMLPurifier.auto.load');
-    $config = $HTMLPurifier_Config::createDefault();
-    $config->set('Core', 'Encoding', 'ISO-8859-1'); //Remplacez par votre
-    encodage
-    $config->set('Core', 'XHTML', true); //Remplacer par false si HTML 4.01
-    $purificateur = new HTMLPurifier($config);
-    $html_propre = $purificateur->purify($html_a_purifier);

-- Compatibility fixes for HHVM.  Thanks Mateusz Turcza for contributing
-  this fix.
-- HTML Purifier now never defines __autoload, fixing #196.  Thanks
-  Michael Kliewe for reporting.
-- In some situations, Config.php would report an undefined index: class
-  error; this has been fixed.  Thanks DiLong Fa for contributing
-  this fix.
-- We no longer produce <script /> tags; we always explicitly write
-  out the open and close tag.  Thanks Dimitri Gritsajuk
-  <gritsajuk.dimitri@gmail.com> for contributing this fix.
-- Better compatibility when IDNA constants are not present.  Thanks
-  Mateusz Turcza <xemlock@gmail.com> for contributing this fix.
-
-4.10.0, released 2018-02-22
-# PHP 5.3 is no longer officially supported by HTML Purifier
-  (we did not specifically break support, but we are no longer
-  testing on PHP 5.3)
-! Relative CSS length units are now supported
-- A few PHP 7.2 compatibility fixes, thanks John Flatness
-  <john@zerocrates.org>
-- Improve portability with old versions of libxml which don't
-  support accessing the data of a node
-- IDNA2008 is now used for converting domains to ASCII, fixing
-  some rather strange bugs with international domains
-- Fix race condition resulting in E_WARNING when creating
-  directories with Serializer
-
-4.9.3, released 2017-06-02
-- Workaround PHP 7.1 infinite loop when opcode cache is enabled.
-  Thanks @Xiphin (#134, #135)
-- Don't use autoloader when testing for DOMDocument.  Hypothetically,
-  this could cause your install to start using DirectLex if you had
-  previously been monkeypatching in a custom, autoloaded implementation
-  of DOMDocument.  Don't do that.  Thanks @Izumi-kun (#130)
-
-4.9.2, released 2017-03-12
-- Fixes PHP 5.3 compatibility
-- Fix breakage when decoding decimal entities.  Thanks @rybakit (#129)
-
-4.9.1, released 2017-03-08
-! %URI.DefaultScheme can now be set to null, in which case
-  all relative paths are removed.
-! New CSS properties: min-width, max-width, min-height, max-height (#94)
-! Transparency (rgba) and hsl/hsla supported where color CSS is present.
-  Thanks @fxbt for contributing the patch. (#118)
-- When idn_to_ascii is defined, we might accept malformed
-  hostnames.  Apply validation to the result in such cases.
-- Close directory when done in Serializer DefinitionCache (#100)
-- Deleted some asserts to avoid linters from choking (#97)
-- Rework Serializer cache behavior to avoid chmod'ing if possible (#32)
-- Embedded semicolons in strings in CSS are now handled correctly!
-- We accidentally dropped certain Unicode characters if there was
-  one or more invalid characters.  This has been fixed, thanks
-  to mpyw <ryosuke_i_628@yahoo.co.jp>
-- Fix for "Don't truncate upon encountering </div> when using DOMLex"
-  caused a regression with HTML 4.01 Strict parsing with libxml 2.9.1
-  (and maybe later versions, but known OK with libxml 2.9.4).  The
-  fix is to go about handling truncation a bit more cleverly so that
-  we can wrap with divs (sidestepping the bug) but slurping out the
-  rest of the text in case it ran off the end.  (#78)
-- Fix PREG_BACKTRACK_LIMIT_ERROR in HTMLPurifier_Filter_ExtractStyle.
-  Thanks @breathbath for contributing the report and fix (#120)
-- Fix entity decoding algorithm to be more conservative about
-  decoding entities that are missing trailing semicolon.
-  To get old behavior, set %Core.LegacyEntityDecoder to true.
-  (#119)
-- Workaround libxml bug when HTML tags are embedded inside
-  script tags.  To disable workaround set %Core.AggressivelyRemoveScript
-  to false. (#83)
-# By default, when a link has a target attribute associated
-  with it, we now also add rel="noopener" in order to
-  prevent the new window from being able to overwrite
-  the original frame.  To disable this protection,
-  set %HTML.TargetNoopener to FALSE.
-
-4.9.0 was cut on Git but never properly released; when we did the
-real release we decided to skip this version number.
-
-4.8.0, released 2016-07-16
-# By default, when a link has a target attribute associated
-  with it, we now also add rel="noreferrer" in order to

-  set %HTML.TargetNoreferrer to FALSE.
-! Full PHP 7 compatibility, the test suite is ALL GO.
-! %CSS.AllowDuplicates permits duplicate CSS properties.
-! Support for 'tel' URIs.
-! Partial support for 'border-radius' properties when %CSS.AllowProprietary is true.
-  The slash syntax, i.e., 'border-radius: 2em 1em 4em / 0.5em 3em' is not
-  yet supported.
-! %Attr.ID.HTML5 turns on HTML5-style ID handling.
-- alt truncation could result in malformed UTF-8 sequence. Don't
-  truncate.  Thanks Brandon Farber for reporting.

-- Support non-/tmp temporary directories for data:// validation
-- Give a better error message when a user attempts to allow
-  ul/ol without allowing li.
-- On some versions of PHP, the Serializer DefinitionCache could
-  infinite loop when the directory exists but is not listable. (#49)
-- Don't match for <body> inside comments with
-  %Core.ConvertDocumentToFragment. (#67)
-- SafeObject is now less case sensitive. (#57)
-- AutoFormat.RemoveEmpty.Predicate now correctly renders in
-  web form. (#85)
-
-4.7.0, released 2015-08-04
-# opacity is now considered a "tricky" CSS property rather than a
-  proprietary one.
-! %AutoFormat.RemoveEmpty.Predicate for specifying exactly when
-  an element should be considered "empty" (maybe preserve if it
-  has attributes), and modify iframe support so that the iframe
-  is removed if it is missing a src attribute.  Thanks meeva for
-  reporting.
-- Don't truncate upon encountering </div> when using DOMLex.  Thanks
-  Myrto Christina for finally convincing me to fix this.
-- Update YouTube filter for new code.
-- Fix parsing of rgb() values with spaces in them for 'border'
-  attribute.
-- Don't remove foo="" attributes if foo is a boolean attribute.  Thanks
-  valME for reporting.
-
-4.6.0, released 2013-11-30
-# Secure URI munge hashing algorithm has changed to hash_hmac("sha256", $url, $secret).
-  Please update any verification scripts you may have.
-# URI parsing algorithm was made more strict, so only prefixes which
-  looks like schemes will actually be schemes.  Thanks
-  Michael Gusev <mgusev@sugarcrm.com> for fixing.
-# %Core.EscapeInvalidChildren is no longer supported, and no longer does
-  anything.
-! New directive %Core.AllowHostnameUnderscore which allows underscores
-  in hostnames.
-- Eliminate quadratic behavior in DOMLex by using a proper queue.
-  Thanks Ole Laursen for noticing this.
-- Rewritten MakeWellFormed/FixNesting implementation eliminates quadratic
-  behavior in the rest of the purificaiton pipeline.  Thanks Chedburn
-  Networks for sponsoring this work.
-- Made Linkify URL parser a bit less permissive, so that non-breaking
-  spaces and commas are not included as part of URL.  Thanks nAS for fixing.
-- Fix some bad interactions with %HTML.Allowed and injectors.  Thanks
-  David Hirtz for reporting.
-- Fix infinite loop in DirectLex. Thanks Ashar Javed (@soaj1664ashar)
-  for reporting.
-
-4.5.0, released 2013-02-17
-# Fix bug where stacked attribute transforms clobber each other;
-  this also means it's no longer possible to override attribute
-  transforms in later modules.  No internal code was using this
-  but this may break some clients.
-# We now use SHA-1 to identify cached definitions, instead of MD5.
-! Support display:inline-block
-! Support for more white-space CSS values.
-! Permit underscores in font families
-! Support for page-break-* CSS3 properties when proprietary properties
-  are enabled.
-! New directive %Core.DisableExcludes; can be set to 'true' to turn off
-  SGML excludes checking.  If HTML Purifier is removing too much text
-  and you don't care about full standards compliance, try setting this to
-  'true'.
-- Use prepend for SPL autoloading on PHP 5.3 and later.
-- Fix bug with nofollow transform when pre-existing rel exists.
-- Fix bug where background:url() always gets lower-cased
-  (but not background-image:url())

-- Don't remove certain empty tags on RemoveEmpty.
-
-4.4.0, released 2012-01-18
-# Removed PEARSax3 handler.
-# URI.Munge now munges URIs inside the same host that go from https
-  to http.  Reported by Neike Taika-Tessaro.
-# Core.EscapeNonASCIICharacters now always transforms entities to
-  entities, even if target encoding is UTF-8.
-# Tighten up selector validation in ExtractStyleBlocks.
-  Non-syntactically valid selectors are now rejected, along with
-  some of the more obscure ones such as attribute selectors, the
-  :lang pseudoselector, and anything not in CSS2.1.  Furthermore,
-  ID and class selectors now work properly with the relevant
-  configuration attributes.  Also, mute errors when parsing CSS
-  with CSS Tidy.  Reported by Mario Heiderich and Norman Hippert.
-! Added support for 'scope' attribute on tables.

-  limited allowed comments in untrusted situations.
-! Implement iframes, and allow them to be used in untrusted mode with
-  %HTML.SafeIframe and %URI.SafeIframeRegexp.  Thanks Bradley M. Froehle
-  <brad.froehle@gmail.com> for submitting an initial version of the patch.
-! The Forms module now works properly for transitional doctypes.
-! Added support for internationalized domain names. You need the PEAR
-  Net_IDNA2 module to be in your path; if it is installed, ensure the
-  class can be loaded and then set %Core.EnableIDNA to true.
-- Color keywords are now case insensitive.  Thanks Yzmir Ramirez
-  <yramirez-htmlpurifier@adicio.com> for reporting.
-- Explicitly initialize anonModule variable to null.
-- Do not duplicate nofollow if already present.  Thanks 178
-  for reporting.
-- Do not add nofollow if hostname matches our current host.  Thanks 178
-  for reporting, and Neike Taika-Tessaro for helping diagnose.
-- Do not unset parser variable; this fixes intermittent serialization
-  problems.  Thanks Neike Taika-Tessaro for reporting, bill
-  <10010tiger@gmail.com> for diagnosing.
-- Fix iconv truncation bug, where non-UTF-8 target encodings see
-  output truncated after around 8000 characters.  Thanks Jörg Ludwig
-  <joerg.ludwig@iserv.eu> for reporting.
-- Fix broken table content model for XHTML1.1 (and also earlier
-  versions, although the W3C validator doesn't catch those violations).
-  Thanks GlitchMr <glitch.mr@gmail.com> for reporting.
-
-4.3.0, released 2011-03-27
-# Fixed broken caching of customized raw definitions, but requires an
-  API change.  The old API still works but will emit a warning,
-  see http://htmlpurifier.org/docs/enduser-customize.html#optimized
-  for how to upgrade your code.
-# Protect against Internet Explorer innerHTML behavior by specially
-  treating attributes with backticks but no angled brackets, quotes or
-  spaces.  This constitutes a slight semantic change, which can be
-  reverted using %Output.FixInnerHTML.  Reported by Neike Taika-Tessaro
-  and Mario Heiderich.
-# Protect against cssText/innerHTML by restricting allowed characters
-  used in fonts further than mandated by the specification and encoding
-  some extra special characters in URLs.  Reported by Neike
-  Taika-Tessaro and Mario Heiderich.
-! Added %HTML.Nofollow to add rel="nofollow" to external links.
-! More types of SPL autoloaders allowed on later versions of PHP.
-! Implementations for position, top, left, right, bottom, z-index
-  when %CSS.Trusted is on.

-- Switch to an iterative traversal of the DOM, which prevents us
-  from running out of stack space for deeply nested documents.
-  Thanks Maxim Krizhanovsky for contributing a patch.
-- Make removal of conditional IE comments ungreedy; thanks Bernd
-  for reporting.
-- Escape CDATA before removing Internet Explorer comments.
-- Fix removal of id attributes under certain conditions by ensuring
-  armor attributes are preserved when recreating tags.
-- Check if schema.ser was corrupted.
-- Check if zend.ze1_compatibility_mode is on, and error out if it is.
-  This safety check is only done for HTMLPurifier.auto.php; if you
-  are using standalone or the specialized includes files, you're
-  expected to know what you're doing.
-- Stop repeatedly writing the cache file after I'm done customizing a
-  raw definition.  Reported by ajh.
-- Switch to using require_once in the Bootstrap to work around bad
-  interaction with Zend Debugger and APC.  Reported by Antonio Parraga.
-- Fix URI handling when hostname is missing but scheme is present.
-  Reported by Neike Taika-Tessaro.
-- Fix missing numeric entities on DirectLex; thanks Neike Taika-Tessaro

-
-4.2.0, released 2010-09-15
-! Added %Core.RemoveProcessingInstructions, which lets you remove

-  did nothing.  Thanks David Rothstein for reporting.
-! Add documentation about configuration directive types.
-! Add %CSS.ForbiddenProperties configuration directive.
-! Add %HTML.FlashAllowFullScreen to permit embedded Flash objects
-  to utilize full-screen mode.

-  by parser.  Thanks zmonteca for reporting.
-- Fix missing attributes bug when running on Mac Snow Leopard and APC.
-  Thanks sidepodcast for the fix.
-- Warn if an element is allowed, but an attribute it requires is
-  not allowed.
-
-4.1.1, released 2010-05-31
-- Fix undefined index warnings in maintenance scripts.
-- Fix bug in DirectLex for parsing elements with a single attribute
-  with entities.
-- Rewrite CSS output logic for font-family and url().  Thanks Mario
-  Heiderich <mario.heiderich@googlemail.com> for reporting and Takeshi
-  Terada <t-terada@violet.plala.or.jp> for suggesting the fix.
-- Emit an error for CollectErrors if a body is extracted

-  explicitly call it with php.
-- Make test script less chatty when log_errors is on.
-
-4.1.0, released 2010-04-26

-! Handle <ol><ol> properly, by inserting the necessary <li> tag.
-- Always quote the insides of url(...) in CSS.
-
-4.0.0, released 2009-07-07
-# APIs for ConfigSchema subsystem have substantially changed. See
-  docs/dev-config-bcbreaks.txt for details; in essence, anything that
-  had both namespace and directive now have a single unified key.
-# Some configuration directives were renamed, specifically:
-    %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL
-    %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
-    %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
-    %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl
-  As usual, the old directive names will still work, but will throw E_NOTICE
-  errors.
-# The allowed values for class have been relaxed to allow all of CDATA for
-  doctypes that are not XHTML 1.1 or XHTML 2.0.  For old behavior, set
-  %Attr.ClassUseCDATA to false.
-# Instead of appending the content model to an old content model, a blank
-  element will replace the old content model.  You can use #SUPER to get
-  the old content model.
-! More robust support for name="" and id=""
-! HTMLPurifier_Config::inherit($config) allows you to inherit one
-  configuration, and have changes to that configuration be propagated
-  to all of its children.
-! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
-  the name attribute when set. Use with care. Thanks Ian Cook for
-  sponsoring.
-! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
-  tags that contain non-breaking spaces as well other whitespace. You
-  can also modify which tags should have &nbsp; maintained with
-  %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
-! Implement %Attr.AllowedClasses, which allows administrators to restrict
-  classes users can use to a specified finite set of classes, and
-  %Attr.ForbiddenClasses, which is the logical inverse.
-! You can now maintain your own configuration schema directories by
-  creating a config-schema.php file or passing an extra argument. Check
-  docs/dev-config-schema.html for more details.
-! Added HTMLPurifier_Config->serialize() method, which lets you save away
-  your configuration in a compact serial file, which you can unserialize
-  and use directly without having to go through the overhead of setup.
-- Fix bug where URIDefinition would not get cleared if it's directives got
-  changed.
-- Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
-- Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
-- Make %URI.Munge not apply to links that have the same host as your host.
-- Prevent stray </body> tag from truncating output, if a second </body>
-  is present.
-. Created script maintenance/rename-config.php for renaming a configuration
-  directive while maintaining its alias.  This script does not change source code.
-. Implement namespace locking for definition construction, to prevent
-  bugs where a directive is used for definition construction but is not
-  used to construct the cache hash.
-
-3.3.0, released 2009-02-16
-! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
-! Implement generic property list classess
-- Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
-  does not do the "right thing" with characters not supported in the output
-  set.
-- Spellcheck UTF-8: The Secret To Character Encoding
-- Fix improper removal of the contents of elements with only whitespace. Thanks
-  Eric Wald for reporting.
-- Fix broken test suite in versions of PHP without spl_autoload_register()
-- Fix degenerate case with YouTube filter involving double hyphens.
-  Thanks Pierre Attar for reporting.
-- Fix YouTube rendering problem on certain versions of Firefox.
-- Fix CSSDefinition Printer problems with decorators
-- Add text parameter to unit tests, forces text output
-. Add verbose mode to command line test runner, use (--verbose)
-. Turn on unit tests for UnitConverter
-. Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
-. Fix newline errors that caused spurious failures when CRLF HTML Purifier was
-  tested on Linux.
-. Removed trailing whitespace from all text files, see
-  remote-trailing-whitespace.php maintenance script.
-. Convert configuration to use property list backend.
-
-3.2.0, released 2008-10-31
-# Using %Core.CollectErrors forces line number/column tracking on, whereas
-  previously you could theoretically turn it off.
-# HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
-  use handleEnd() instead.
-! %Output.AttrSort for when you need your attributes in alphabetical order to
-  deal with a bug in FCKEditor. Requested by frank farmer.
-! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
-! Proper support for name attribute. It is now allowed and equivalent to the id
-  attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
-  is heavy (for all doctypes).
-! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
-  use on hand-written HTML.
-! Add error-cases for unsupported elements in MakeWellFormed. This enables
-  the strategy to be used, standalone, on untrusted input.
-! %Core.AggressivelyFixLt is on by default. This causes more sensible
-  processing of left angled brackets in smileys and other whatnot.
-! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
-  'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
-  the --only-phpt parameter, although for backwards-compatibility the flag
-  will still work.
-! AutoParagraph auto-formatter will now preserve double-newlines upon output.
-  Users who are not performing inbound filtering, this may seem a little
-  useless, but as a bonus, the test suite and handling of edge cases is also
-  improved.
-! Experimental implementation of forms for %HTML.Trusted
-! Track column numbers when maintain line numbers is on
-! Proprietary 'background' attribute on table-related elements converted into
-  corresponding CSS.  Thanks Fusemail for sponsoring this feature!
-! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
-  supertype.
-! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
-  time of operation varies slightly from notifyEnd() as *all* end tokens are
-  processed by the injector before they are subject to the well-formedness rules.
-! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
-  basename of image when not present.
-! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
-- Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
-  the other involving an undefined $is_folder error.
-- Throw error when %Core.Encoding is set to a spurious value. Previously,
-  this errored silently and returned false.
-- Redirected stderr to stdout for flush error output.
-- %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
-  available.
-- Do not re-munge URL if the output URL has the same host as the input URL.
-  Requested by Chris.
-- Fix error in documentation regarding %Filter.ExtractStyleBlocks
-- Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
-- Fix bug with inline elements in blockquotes conflicting with strict doctype
-- Detect if HTML support is disabled for DOM by checking for loadHTML() method.
-- Fix bug where dots and double-dots in absolute URLs without hostname were
-  not collapsed by URIFilter_MakeAbsolute.
-- Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
-  by reordering their addition.
-- Will now throw exception on many error conditions during lexer creation; also
-  throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
-  is being used.
-- Detect if domxml extension is loaded, and use DirectLEx accordingly.
-- Improve handling of big numbers with floating point arithmetic in UnitConverter.
-  Reported by David Morton.
-. Strategy_MakeWellFormed now operates in-place, saving memory and allowing
-  for more interesting filter-backtracking
-. New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
-  index to reprocess tokens.
-. StringHashParser now allows for multiline sections with "empty" content;
-  previously the section would remain undefined.
-. Added --quick option to multitest.php, which tests only the most recent
-  release for each series.
-. Added --distro option to multitest.php, which accepts either 'normal' or
-  'standalone'. This supercedes --exclude-normal and --exclude-standalone
-
-3.1.1, released 2008-06-19
-# %URI.Munge now, by default, does not munge resources (for example, <img src="">)
-  In order to enable this again, please set %URI.MungeResources to true.
-! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
-  and height/width HTML with %HTML.MaxImgLength.
-! %URI.MungeSecretKey for secure URI munging. Thanks Chris
-  for sponsoring this feature. Check out the corresponding documentation
-  for details. (Att Nightly testers: The API for this feature changed before
-  the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
-  %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
-! Implemented post URI filtering. Set member variable $post to true to set
-  a URIFilter as such.
-! Allow modules to define injectors via $info_injector. Injectors are
-  automatically disabled if injector's needed elements are not found.
-! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
-  Thanks Chris for sponsoring. If you've been using ad hoc code from the
-  forums, PLEASE use this instead.
-! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
-  embedded, tag name, attribute name, CSS property name). See %URI.Munge
-  for more details. Requested by Jochem Blok.
-- Disable percent height/width attributes for img.
-- AttrValidator operations are now atomic; updates to attributes are not
-  manifest in token until end of operations. This prevents naughty internal
-  code from directly modifying CurrentToken when they're not supposed to.
-  This semantics change was requested by frank farmer.
-- Percent encoding checks enabled for URI query and fragment
-- Fix stray backslashes in font-family; CSS Unicode character escapes are
-  now properly resolved (although *only* in font-family). Thanks Takeshi Terada
-  for reporting.
-- Improve parseCDATA algorithm to take into account newline normalization
-- Account for browser confusion between Yen character and backslash in
-  Shift_JIS encoding. This fix generalizes to any other encoding which is not
-  a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
-- Fix missing configuration parameter in Generator calls. Thanks vs for the
-  partial patch.
-- Improved adherence to Unicode by checking for non-character codepoints.
-  Thanks Geoffrey Sneddon for reporting. This may result in degraded
-  performance for extremely large inputs.
-- Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
-  for reporting.
-. Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
-  handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
-  this class.
-. API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
-  to __construct($min, $max). __construct(true) is equivalent to
-  __construct('0').
-. Added HTMLPurifier_AttrDef_Switch class
-. Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
-  up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
-  get this called with the configuration object.  All modules now
-  use this rather than __construct(), although legacy code using constructors
-  will still work--the new format, however, lets modules access the
-  configuration object for HTML namespace dependant tweaks.
-. AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
-. ConfigSchema data-structure heavily optimized; on average it uses a third
-  the memory it did previously. The interface has changed accordingly,
-  consult changes to HTMLPurifier_Config for details.
-. Variable parsing types now are magic integers instead of strings
-. Added benchmark for ConfigSchema
-. HTMLPurifier_Generator requires $config and $context parameters. If you
-  don't know what they should be, use HTMLPurifier_Config::createDefault()
-  and new HTMLPurifier_Context().
-. Printers now properly distinguish between output configuration, and
-  target configuration. This is not applicable to scripts using
-  the Printers for HTML Purifier related tasks.
-. HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
-  fatal errors will ensue.
-. URIFilter->prepare can return false in order to abort loading of the filter
-. Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
-  an external resource.
-. %URI.Munge functionality factored out into a post-filter class.
-. Added CurrentCSSProperty context variable during CSS validation

-3.1.0, released 2008-05-18
-# Unnecessary references to objects (vestiges of PHP4) removed from method
-  signatures.  The following methods do not need references when assigning from
-  them and will result in E_STRICT errors if you try:
-    + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
-    + HTMLPurifier_ConfigSchema::instance()
-    + HTMLPurifier_DefinitionCacheFactory::instance()
-    + HTMLPurifier_DefinitionCacheFactory->create()
-    + HTMLPurifier_DoctypeRegistry->register()
-    + HTMLPurifier_DoctypeRegistry->get()
-    + HTMLPurifier_HTMLModule->addElement()
-    + HTMLPurifier_HTMLModule->addBlankElement()
-    + HTMLPurifier_LanguageFactory::instance()
-# Printer_ConfigForm's get*() functions were static-ified
-# %HTML.ForbiddenAttributes requires attribute declarations to be in the
-  form of tag@attr, NOT tag.attr (which will throw an error and won't do
-  anything). This is for forwards compatibility with XML; you'd do best
-  to migrate an %HTML.AllowedAttributes directives to this syntax too.
-! Allow index to be false for config from form creation
-! Added HTMLPurifier::VERSION constant
-! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
-  and allows for version numbers like "3.1.0-dev".
-! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
-! HTML Purifier's URI handling is a lot more robust, with much stricter
-  validation checks and better percent encoding handling. Thanks Gareth Heyes
-  for indicating security vulnerabilities from lax percent encoding.
-! Bootstrap autoloader deals more robustly with classes that don't exist,
-  preventing class_exists($class, true) from barfing.

-- Created directories are now chmod'ed properly
-- Fixed bug with fallback languages in LanguageFactory
-- Standalone testing setup properly with autoload
-. Out-of-date documentation revised

-. HTMLPurifier_Error removed in favor of exceptions
-. More copy() function removed; should use clone instead
-. More extensive unit tests for HTMLDefinition
-. assertPurification moved to central harness
-. HTMLPurifier_Generator accepts $config and $context parameters during
-  instantiation, not runtime
-. Double-quotes outside of attribute values are now unescaped
-
-3.1.0rc1, released 2008-04-22
-# Autoload support added. Internal require_once's removed in favor of an
-  explicit require list or autoloading. To use HTML Purifier,
-  you must now either use HTMLPurifier.auto.php
-  or HTMLPurifier.includes.php; setting the include path and including
-  HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
-  as well to register our autoload handler (or modify your autoload function
-  to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
-  HTMLPurifier.safe-includes.php for a less performance friendly but more
-  user-friendly library load.
-# HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
-  information is stored in the ConfigSchema directory, and the
-  maintenance/generate-schema-cache.php generates the schema.ser file, which
-  is now instantiated. Support for userland schema changes coming soon!
-# HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
-  alias; to get rid of these errors just modify your configuration to use
-  the new directive name.
-# HTMLPurifier->addFilter is deprecated; built-in filters can now be
-  enabled using %Filter.$filter_name or by setting your own filters using
-  %Filter.Custom
-# Directive-level safety properties superceded in favor of module-level
-  safety. Internal method HTMLModule->addElement() has changed, although
-  the externally visible HTMLDefinition->addElement has *not* changed.
-! Extra utility classes for testing and non-library operations can
-  be found in extras/. Specifically, these are FSTools and ConfigDoc.
-  You may find a use for these in your own project, but right now they
-  are highly experimental and volatile.
-! Integration with PHPT allows for automated smoketests
-! Limited support for proprietary HTML elements, namely <marquee>, sponsored
-  by Chris. You can enable them with %HTML.Proprietary if your client
-  demands them.
-! Support for !important CSS cascade modifier. By default, this will be stripped
-  from CSS, but you can enable it using %CSS.AllowImportant
-! Support for display and visibility CSS properties added, set %CSS.AllowTricky
-  to true to use them.
-! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
-  Developer error (not enduser error) can cause these to be triggered.
-! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
-! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
-  mucking around with HTMLPurifier_CSSDefinition
-! ConfigDoc output has been enhanced with version and deprecation info.
-! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
-- Autoclose now operates iteratively, i.e. <span><span><div> now has
-  both span tags closed.
-- Various HTMLPurifier_Config convenience functions now accept another parameter
-  $schema which defines what HTMLPurifier_ConfigSchema to use besides the
-  global default.
-- Fix bug with trusted script handling in libxml versions later than 2.6.28.
-- Fix bug in ExtractStyleBlocks with comments in style tags
-- Fix bug in comment parsing for DirectLex

-  on the same element without emitting errors.
-- Fixed fatal error in PH5P lexer with invalid tag names
-. Plugins now get their own changelogs according to project conventions.
-. Convert tokens to use instanceof, reducing memory footprint and
-  improving comparison speed.
-. Dry runs now supported in SimpleTest; testing facilities improved
-. Bootstrap class added for handling autoloading functionality
-. Implemented recursive glob at FSTools->globr
-. ConfigSchema now has instance methods for all corresponding define*
-  static methods.
-. A couple of new historical maintenance scripts were added.
-. HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
-. tests/index.php can now be run from any directory.
-. HTMLPurifier_Token subclasses split into seperate files
-. HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
-. HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
-. New --php=php flag added, allows PHP executable to be specified (command
-  line only!)
-. htmlpurifier_add_test() preferred method to translate test files in to
-  classes, because it handles PHPT files too.
-. Debugger class is deprecated and will be removed soon.
-. Command line argument parsing for testing scripts revamped, now --opt value
-  format is supported.
-. Smoketests now cleanup after magic quotes
-. Generator now can output comments (however, comments are still stripped
-  from HTML Purifier output)
-. HTMLPurifier_ConfigSchema->validate() deprecated in favor of
-  HTMLPurifier_VarParser->parse()
-. Integers auto-cast into float type by VarParser.
-. HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only
-  during cache generation
-. Reordered script calls in maintenance/flush.php
-. Command line scripts now honor exit codes
-. When --flush fails in unit testers, abort tests and print message
-. Improved documentation in docs/dev-flush.html about the maintenance scripts
-. copy() methods removed in favor of clone keyword
-
-3.0.0, released 2008-01-06

-
-2.1.2, released 2007-09-03
-! Implemented Object module for trusted users
-! Implemented experimental HTML5 parsing mode using PH5P. To use, add
-  this to your code:
-        require_once 'HTMLPurifier/Lexer/PH5P.php';
-        $config->set('Core', 'LexerImpl', 'PH5P');
-  Note that this Lexer introduces some classes not in the HTMLPurifier
-  namespace.  Also, this is PHP5 only.
-! CSS property border-spacing implemented
-- Fix non-visible parsing error in DirectLex with empty tags that have
-  slashes inside attribute values.
-- Fix typo in CSS definition: border-collapse:seperate; was incorrectly
-  accepted as valid CSS. Usually non-visible, because this styling is the
-  default for tables in most browsers. Thanks Brett Zamir for pointing
-  this out.
-- Fix validation errors in configuration form
-- Hammer out a bunch of edge-case bugs in the standalone distribution

-
-2.1.0, released 2007-08-02
-# flush-htmldefinition-cache.php superseded in favor of a generic
-  flush-definition-cache.php script, you can clear a specific cache
-  by passing its name as a parameter to the script
-! Phorum mod implemented for HTML Purifier
-! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
-  trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
-  for PHP4 (DirectLex).
-! Standalone file now available, which greatly reduces the amount of
-  includes (although there are still a few files that reside in the
-  standalone folder)
-! Relative URIs can now be transformed into their absolute equivalents

-  %HTML.Allowed
-. ConfigForm generates textareas instead of text inputs for lists, hashes,
-  lookups, text and itext fields

-  be used to customize this behavior, by default <script> and <style> are
-  hidden
-. Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
-. Custom ChildDef added to default include list
-. URIScheme reflection improved: will not attempt to include file if class
-  already exists. May clobber autoload, so I need to keep an eye on it
-. ConfigSchema heavily optimized, will only collect information and validate
-  definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
-. AttrDef_URI unit tests and implementation refactored
-. benchmarks/ directory now protected from public view with .htaccess file;

-  linkify your HTML input by setting %AutoFormat.AutoParagraph and
-  %AutoFormat.Linkify to true
-! Newlines normalized internally, and then converted back to the
-  value of PHP_EOL. If this is not desired, set your newline format
-  using %Output.Newline.

-  cases involving Lexing or Strategies
-- Clean up special case code for <script> tags
-- Reorder includes for DefinitionCache decorators, fixes a possible
-  missing class error
-- Fixed bug where manually modified definitions were not saved via cache
-  (mostly harmless, except for the fact that it would be a little slower)

-  information
-# Transform modules changed to Tidy modules, which offer more flexibility
-  and better modularization

-  performed on it, ensuring that its internal state stays consistent.
-  To revert this behavior, you can set the $autoFinalize member variable
-  off, but it's not recommended.
-# New compact syntax for AttrDef objects that can be used to instantiate
-  new objects via make()
-# Definitions (esp. HTMLDefinition) are now cached for a significant
-  performance boost. You can disable caching by setting %Core.DefinitionCache

-# ID attributes now disabled by default. New directives:
-  + %HTML.EnableAttrID - restores old behavior by allowing IDs
-  + %Attr.IDPrefix - %Attr.IDBlacklist alternative that munges all user IDs
-    so that they don't collide with your IDs

-
-1.1.1, released 2006-09-24

-= KEY ====================
-    # Flagship
-    - Regular
-    ? Maybe I'll Do It
-==========================
-
-If no interest is expressed for a feature that may require a considerable
-amount of effort to implement, it may get endlessly delayed. Do not be
-afraid to cast your vote for the next feature to be implemented!
-
-Things to do as soon as possible:
-
- - http://htmlpurifier.org/phorum/read.php?3,5560,6307#msg-6307
- - Think about allowing explicit order of operations hooks for transforms
- - Fix "<.<" bug (trailing < is removed if not EOD)
- - Build in better internal state dumps and debugging tools for remote
-   debugging
- - Allowed/Allowed* have strange interactions when both set
- ? Transform lone embeds into object tags
- - Deprecated config options that emit warnings when you set them (with'
-   a way of muting the warning if you really want to)
- - Make HTML.Trusted work with Output.FlashCompat
- - HTML.Trusted and HTML.SafeObject have funny interaction; general
-   problem is what to do when a module "supersedes" another
-   (see also tables and basic tables.)  This is a little dicier
-   because HTML.SafeObject has some extra functionality that
-   trusted might find useful.  See http://htmlpurifier.org/phorum/read.php?3,5762,6100
-
-FUTURE VERSIONS
----------------
-
-4.9 release [OMG CONFIG PONIES]
- ! Fix Printer. It's from the old days when we didn't have decent XML classes
- ! Factor demo.php into a set of Printer classes, and then create a stub
-   file for users here (inside the actual HTML Purifier library)
- - Fix error handling with form construction
- - Do encoding validation in Printers, or at least, where user data comes in
- - Config: Add examples to everything (make built-in which also automatically
-   gives output)
- - Add "register" field to config schemas to eliminate dependence on
-   naming conventions (try to remember why we ultimately decided on tihs)
-
-5.0 release [HTML 5]
- # Swap out code to use html5lib tokenizer and tree-builder
- ! Allow turning off of FixNesting and required attribute insertion
-
-5.1 release [It's All About Trust] (floating)
- # Implement untrusted, dangerous elements/attributes
- # Implement IDREF support (harder than it seems, since you cannot have
-   IDREFs to non-existent IDs)
-     - Implement <area> (client and server side image maps are blocking
-       on IDREF support)
- # Frameset XHTML 1.0 and HTML 4.01 doctypes
- - Figure out how to simultaneously set %CSS.Trusted and %HTML.Trusted (?)
-
-5.2 release [Error'ed]
- # Error logging for filtering/cleanup procedures
- # Additional support for poorly written HTML
-    - Microsoft Word HTML cleaning (i.e. MsoNormal, but research essential!)
-    - Friendly strict handling of <address> (block -> <br>)
- - XSS-attempt detection--certain errors are flagged XSS-like
- - Append something to duplicate IDs so they're still usable (impl. note: the
-   dupe detector would also need to detect the suffix as well)
-
-6.0 release [Beyond HTML]
- # Legit token based CSS parsing (will require revamping almost every
-   AttrDef class). Probably will use CSSTidy
- # More control over allowed CSS properties using a modularization
- # IRI support (this includes IDN)
- - Standardize token armor for all areas of processing
-
-7.0 release [To XML and Beyond]
- - Extended HTML capabilities based on namespacing and tag transforms (COMPLEX)
-    - Hooks for adding custom processors to custom namespaced tags and
-      attributes, offer default implementation
-    - Lots of documentation and samples
-
-Ongoing
- - More refactoring to take advantage of PHP5's facilities
- - Refactor unit tests into lots of test methods
- - Plugins for major CMSes (COMPLEX)
-    - phpBB
-    - Also, a FAQ for extension writers with HTML Purifier
-
-AutoFormat
- - Smileys
- - Syntax highlighting (with GeSHi) with <pre> and possibly <?php
- - Look at http://drupal.org/project/Modules/category/63 for ideas
-
-Neat feature related
- ! Support exporting configuration, so users can easily tweak settings
-   in the demo, and then copy-paste into their own setup
- - Advanced URI filtering schemes (see docs/proposal-new-directives.txt)
- - Allow scoped="scoped" attribute in <style> tags; may be troublesome
-   because regular CSS has no way of uniquely identifying nodes, so we'd
-   have to generate IDs
- - Explain how to use HTML Purifier in non-PHP languages / create
-   a simple command line stub (or complicated?)
- - Fixes for Firefox's inability to handle COL alignment props (Bug 915)
- - Automatically add non-breaking spaces to empty table cells when
-   empty-cells:show is applied to have compatibility with Internet Explorer
- - Table of Contents generation (XHTML Compiler might be reusable). May also
-   be out-of-band information.
- - Full set of color keywords. Also, a way to add onto them without
-   finalizing the configuration object.
- - Write a var_export and memcached DefinitionCache - Denis
- - Built-in support for target="_blank" on all external links
- - Convert RTL/LTR override characters to <bdo> tags, or vice versa on demand.
-   Also, enable disabling of directionality
- ? Externalize inline CSS to promote clean HTML, proposed by Sander Tekelenburg
- ? Remove redundant tags, ex. <u><u>Underlined</u></u>. Implementation notes:
-    1. Analyzing which tags to remove duplicants
-    2. Ensure attributes are merged into the parent tag
-    3. Extend the tag exclusion system to specify whether or not the
-    contents should be dropped or not (currently, there's code that could do
-    something like this if it didn't drop the inner text too.)
- ? Make AutoParagraph also support paragraph-izing double <br> tags, and not
-   just double newlines.  This is kind of tough to do in the current framework,
-   though, and might be reasonably approximated by search replacing double <br>s
-   with newlines before running it through HTML Purifier.
-
-Maintenance related (slightly boring)
- # CHMOD install script for PEAR installs
- ! Factor out command line parser into its own class, and unit test it
- - Reduce size of internal data-structures (esp. HTMLDefinition)
- - Allow merging configurations.  Thus,
-        a -> b -> default
-        c -> d -> default
-   becomes
-        a -> b -> c -> d -> default
-   Maybe allow more fine-grained tuning of this behavior. Alternatively,
-   encourage people to use short plist depths before building them up.
- - Time PHPT tests
-
-ChildDef related (very boring)
- - Abstract ChildDef_BlockQuote to work with all elements that only
-   allow blocks in them, required or optional
- - Implement lenient <ruby> child validation
-
-Wontfix
- - Non-lossy smart alternate character encoding transformations (unless
-   patch provided)
- - Pretty-printing HTML: users can use Tidy on the output on entire page
- - Native content compression, whitespace stripping: use gzip if this is
-   really important

-WYSIWYG - What You See Is What You Get
-    HTML Purifier: A Pretty Good Fit for TinyMCE and FCKeditor
-
-Javascript-based WYSIWYG editors, simply stated, are quite amazing.  But I've
-always been wary about using them due to security issues: they handle the
-client-side magic, but once you've been served a piping hot load of unfiltered
-HTML, what should be done then?  In some situations, you can serve it uncleaned,
-since you only offer these facilities to trusted(?) authors.
-
-Unfortunantely, for blog comments and anonymous input, BBCode, Textile and
-other markup languages still reign supreme.  Put simply: filtering HTML is
-hard work, and these WYSIWYG authors don't offer anything to alleviate that
-trouble.  Therein lies the solution:
-
-HTML Purifier is perfect for filtering pure-HTML input from WYSIWYG editors.
-
-Enough said.

-HTML Purifier Extras
-    The Method Behind The Madness!
-
-The extras/ folder in HTML Purifier contains--you guessed it--extra things
-for HTML Purifier.  Specifically, these are two extra libraries called
-FSTools and ConfigSchema.  They're extra for a reason: you don't need them
-if you're using HTML Purifier for normal usage: filtering HTML.  However,
-if you're a developer, and would like to test HTML Purifier, or need to
-use one of HTML Purifier's maintenance scripts, chances are they'll need
-these libraries. Who knows: maybe you'll find them useful too!
-
-Here are the libraries:
-
-
-FSTools
--------
-
-Short for File System Tools, this is a poor-man's object-oriented wrapper for
-the filesystem. It currently consists of two classes:
-
-- FSTools: This is a singleton that contains a manner of useful functions
-  such as recursive glob, directory removal, etc, as well as the ability
-  to call arbitrary native PHP functions through it like $FS->fopen(...).
-  This makes it a lot simpler to mock these filesystem calls for unit testing.
-
-- FSTools_File: This object represents a single file, and has almost any
-  method imaginable one would need.
-
-Check the files themselves for more information.

-MODx Plugin
-
-MODx <http://www.modxcms.com/> is an open source PHP application framework.
-I first came across them in my referrer logs when tillda asked if anyone
-could implement an HTML Purifier plugin.  This forum thread
-<http://modxcms.com/forums/index.php/topic,6604.0.html> eventually resulted
-in the fruition of this plugin that davidm says, "is on top of my favorite
-list."  HTML Purifier goes great with WYSIWYG editors!
-
-
-
-1. Credits
-
-PaulGregory wrote the overall structure of the code.  I added the
-slashes hack.
-
-
-
-2. Install
-
-First, you need to place HTML Purifier library somewhere.  The code here
-assumes that you've placed in MODx's assets/plugins/htmlpurifier (no version
-number).
-
-Log into the manager, and navigate:
-
-Resources > Manage Resources > Plugins tab > New Plugin
-
-Type in a name (probably HTML Purifier), and copy paste this code into the
-textarea:
-
---------------------------------------------------------------------------------
-$e = &$modx->Event;
-if ($e->name == 'OnBeforeDocFormSave') {
-    global $content;
-
-    include_once '../assets/plugins/htmlpurifier/library/HTMLPurifier.auto.php';
-    $purifier = new HTMLPurifier();
-
-    static $magic_quotes = null;
-    if ($magic_quotes === null) {
-        // this is an ugly hack because this hook hasn't
-        // had the backslashes removed yet when magic_quotes_gpc is on,
-        // but HTMLPurifier must not have the quotes slashed.
-        $magic_quotes = get_magic_quotes_gpc();
-    }
-
-    if ($magic_quotes) $content = stripslashes($content);
-    $content = $purifier->purify($content);
-    if ($magic_quotes) $content = addslashes($content);
-}
---------------------------------------------------------------------------------
-
-Then navigate to the System Events tab and check "OnBeforeDocFormSave".
-Save the plugin.  HTML Purifier now is integrated!
-
-
-
-3. Making sure it works
-
-You can test HTML Purifier by deliberately putting in crappy HTML and seeing
-whether or not it gets fixed.  A better way is to put in something like this:
-
-<p lang="fr">Il est bon</p>
-
-...and seeing whether or not the content comes out as:
-
-<p lang="fr" xml:lang="fr">Il est bon</p>
-
-(lang to xml:lang synchronization is one of the many features HTML Purifier
-has).
-
-
-
-4. Caveat Emptor
-
-This code does not intercept save requests from the QuickEdit plugin, this may
-be added in a later version.  It also modifies things on save, so there's a
-slight chance that HTML Purifier may make a boo-boo and accidently mess things
-up (the original version is not saved).
-
-Finally, make sure that MODx is using UTF-8.  If you are using, say, a French
-localisation, you may be using Latin-1, if that's the case, configure
-HTML Purifier properly like this:
-
-$config = HTMLPurifier_Config::createDefault();
-$config->set('Core', 'Encoding', 'ISO-8859-1'); // or whatever encoding
-$purifier = new HTMLPurifier($config);
-
-
-
-5. Known Bugs
-
-'rn' characters sometimes mysteriously appear after purification. We are
-currently investigating this issue. See: <http://htmlpurifier.org/phorum/read.php?3,1866>
-
-
-
-6. See Also
-
-A modified version of Jot 1.1.3 is available, which integrates with HTML
-Purifier. You can check it out here: <http://modxcms.com/forums/index.php/topic,25621.msg161970.html>

-Install
-    How to install the Phorum HTML Purifier plugin
-
-0. PREREQUISITES
-----------------
-This Phorum module only works on PHP5 and with HTML Purifier 4.0.0
-or later.
-
-1. UNZIP
---------
-Unzip phorum-htmlpurifier-x.y.z, producing an htmlpurifier folder.
-You've already done this step if you're reading this!
-
-2. MOVE
--------
-Move the htmlpurifier folder to the mods/ folder of your Phorum
-installation, so the directory structure looks like:
-
-phorum/
-    mods/
-        htmlpurifier/
-            INSTALL - this install file
-            info.txt, ... - the module files
-            htmlpurifier/
-
-3. INSTALL HTML PURIFIER
-------------------------
-Download and unzip HTML Purifier <htmlpurifier.org>. Place the contents of
-the library/ folder in the htmlpurifier/htmlpurifier folder. Your directory
-structure will look like:
-
-phorum/
-    mods/
-        htmlpurifier/
-            htmlpurifier/
-                HTMLPurifier.auto.php
-                ... - other files
-                HTMLPurifier/
-
-Advanced users:
-    If you have HTML Purifier installed elsewhere on your server,
-    all you need is an HTMLPurifier.auto.php file in the library folder which
-    includes the HTMLPurifier.auto.php file in your install.
-
-4. MIGRATE
-----------
-If you're setting up a new Phorum installation, all you need to do is create
-a blank migrate.php file in the htmlpurifier module folder (NOT the library
-folder.
-
-If you have an old Phorum installation and was using BBCode,
-copy migrate.bbcode.php to migrate.php. If you were using a different input
-format, follow the instructions in migrate.bbcode.php to create your own custom
-migrate.php file.
-
-Your directory structure should now look like this:
-
-phorum/
-    mods/
-        htmlpurifier/
-            migrate.php
-
-5. ENABLE
----------
-Navigate to your Phorum admin panel at http://example.com/phorum/admin.php,
-click on Global Settings > Modules, scroll to "HTML Purifier Phorum Mod" and
-turn it On.
-
-6. MIGRATE SIGNATURES
----------------------
-If you're setting up a new Phorum installation, skip this step.
-
-If you allowed your users to make signatures, navigate to the module settings
-page of HTML Purifier (Global Settings > Modules > HTML Purifier Phorum Mod >
-Configure), type in "yes" in the "Confirm" box, and press "Migrate."
-
-ONLY DO THIS ONCE! BE SURE TO BACK UP YOUR DATABASE!
-
-7. CONFIGURE
-------------
-Configure using Edit settings. See that page for more information.

-HTML Purifier Phorum Mod - Filter your HTML the Standards-Compliant Way!
-
-This Phorum mod enables HTML posting on Phorum.  Under normal circumstances,
-this would cause a huge security risk, but because we are running
-HTML through HTML Purifier, output is guaranteed to be XSS free and
-standards-compliant.
-
-This mod requires HTML input, and previous markup languages need to be
-converted accordingly.  Thus, it is vital that you create a 'migrate.php'
-file that works with your installation. If you're using the built-in
-BBCode formatting, simply move migrate.bbcode.php to that place; for
-other markup languages, consult said file for instructions on how
-to adapt it to your needs.
-
-    -- NOTE -------------------------------------------------
-    You can also run this module in parallel with another
-    formatting module; this module attempts to place itself
-    at the end of the filtering chain. However, if any
-    previous modules produce insecure HTML (for instance,
-    a JavaScript email obfuscator) they will get cleaned.
-
-This module will not work if 'migrate.php' is not created, and an improperly
-made migration file may *CORRUPT* Phorum, so please take your time to
-do this correctly. It should go without saying to *BACKUP YOUR DATABASE*
-before attempting anything here. If no migration is necessary, you can
-simply create a blank migrate.php file. HTML Purifier is smart and will
-not re-migrate already processed messages. However, the original code
-is irretrievably lost (we may change this in the future.)
-
-This module will not automatically migrate user signatures, because this
-process may take a long time. After installing the HTML Purifier module and
-then configuring 'migrate.php', navigate to Settings and click 'Migrate
-Signatures' to migrate all user signatures to HTML.
-
-All of HTML Purifier's usual functions are configurable via the mod settings
-page. If you require custom configuration, create config.php file in
-the mod directory that edits a $config variable. Be sure, also, to
-set $PHORUM['mod_htmlpurifier']['wysiwyg'] to TRUE if you are using a
-WYSIWYG editor (you can do this through a common hook or the web
-configuration form).
-
-Visit HTML Purifier at <http://htmlpurifier.org/>.
