       MKDoc::XML::Stripper - Remove unwanted XML / XHTML tags and attributes

	 use MKDoc::XML::Stripper;

	 my $stripper =	new MKDoc::XML::Stripper;
	 $stripper->allow (qw /p class id/);

	 my $ugly = '<p	class="para" style="color:red">Hello, <strong>World</strong>!</p>';
	 my $neat = $stripper->process_data ($ugly);
	 print $neat;

       Should print:

	 <p class="para">Hello,	World!</p>

       MKDoc::XML::Stripper is a class which lets you specify a	set of tags
       and attributes which you	want to	allow, and then	cheekily strip any XML
       of unwanted tags	and attributes.

       In MKDoc, this is used so that editors use structural XHTML rather than
       presentational tags, i.e. strip anything	which looks like a <font> tag,
       a 'style' attribute or other tags which would break separation of
       structure from content.

       This module does	low level XML manipulation. It will somehow parse even
       broken XML and try to do	something with it. Do not use it unless	you
       know what you're	doing.

   my $stripper	= MKDoc::XML::Stripper->new()
       Instantiates a new MKDoc::XML::Stripper object.

   $stripper->load_def ($def_name);
       Loads a definition located somewhere in @INC under MKDoc/XML/Stripper.

       Available definitions are:

       mkdoc16 - MKDoc 1.6. XHTML structural markup

       You can also load your own definition file, for instance:

	 $stripper->load_def ('my_def.txt');

       Definitions are simple text files as follows:

	 # allow p with	'class'	and id
	 p class
	 p id

	 # allow more stuff
	 td class
	 td id
	 td style

	 # etc...

   $stripper->allow ($tag, @attributes)
       Allows "<$tag>" to appear in the	stripped XML. Additionally, allows
       @attributes to appear as	attributes of <$tag>, so for instance:

	 $stripper->allow ('p',	'class', 'id');

       Will allow the following:

	 <p class="foo">
	 <p id="bar">
	 <p class="foo"	id="bar">

       However any extra attributes will be stripped, i.e.

	 <p class="foo"	id="bar" style="font-color: red">

       Will be rewritten as

	 <p class="foo"	id="bar">

   $stripper->disallow ($tag)
       Explicitly disallows a tag and all its associated attributes.  By
       default everything is disallowed.

   $stripper->process_data ($some_xml);
       Strips $some_xml	according to the rules that were given with the
       allow() and disallow() methods and returns the result. Does not modify
       $some_xml in place.

   $stripper->process_file ('/an/xml/file.xml');
       Strips '/an/xml/file.xml' according to the rules	that were given	with
       the allow() and disallow() methods and returns the result. Does not
       modify '/an/xml/file.xml' in place.

       MKDoc::XML::Stripper does not really parse the XML file you're giving
       to it nor does it care if the XML is well-formed	or not.	It uses
       MKDoc::XML::Tokenizer to	turn the XML / XHTML file into a series	of
       MKDoc::XML::Token objects and strictly operates on a list of tokens.

       For this	same reason MKDoc::XML::Stripper does not support namespaces.
