NAME

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

SYNOPSIS

         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>

SUMMARY

       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.

DISCLAIMER

       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.

API

   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:

       xhtml10frameset
       xhtml10strict
       xhtml10transitional
       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>
         <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.

NOTES

       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.
