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

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

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.
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>
