+module Builder
+
+  # Create a series of SAX-like XML events (e.g. start_tag, end_tag)
+  # from the markup code.  XmlEvent objects are used in a way similar
+  # to XmlMarkup objects, except that a series of events are generated
+  # and passed to a handler rather than generating character-based
+  # markup.
+  #
+  # Usage:
+  #   xe = Builder::XmlEvents.new(hander)
+  #   xe.title("HI")    # Sends start_tag/end_tag/text messages to the handler.
+  #
+  # Indentation may also be selected by providing value for the
+  # indentation size and initial indentation level.
+  #
+  #   xe = Builder::XmlEvents.new(handler, indent_size, initial_indent_level)
+  #
+  # == XML Event Handler
+  #
+  # The handler object must expect the following events.
+  #
+  # [<tt>start_tag(tag, attrs)</tt>]
+  #     Announces that a new tag has been found.  +tag+ is the name of
+  #     the tag and +attrs+ is a hash of attributes for the tag.
+  #
+  # [<tt>end_tag(tag)</tt>]
+  #     Announces that an end tag for +tag+ has been found.
+  #
+  # [<tt>text(text)</tt>]
+  #     Announces that a string of characters (+text+) has been found.
+  #     A series of characters may be broken up into more than one
+  #     +text+ call, so the client cannot assume that a single
+  #     callback contains all the text data.
+  #
+  class XmlEvents < XmlMarkup #:nodoc:
+    def text!(text)
+      @target.text(text)

+    def _start_tag(sym, attrs, end_too=false)
