31    <h2>Modules</h2>
32    
33      <p>Note that all of these modules are <em>work in progress</em>
34      and have <a href="#todo">a number of unresolved problems</a>.</p>
35    
36      <p>Note also that some modules have no documentation for now.</p>
37    
38    <div class=section id=modules-html-xml>
39    <h3>Modules for HTML and XML</h3>
40    
41  <p>It currently contains two Perl modules:</p>  <p id=modules-html>Modules related to HTML and XHTML are as follows:
42    <dl>
43    <dt id=module-whatpm-html><a href="Whatpm/HTML.html"><code>Whatpm::HTML</code></a></dt>
44      <dd>An implementation of HTML5 document and fragment
45      parsing algorithms.  It can be used
46      to convert an arbitrary string into a
47      <abbr title="Document Object Model">DOM</abbr>.  (See also
48      <a href="#demo-html-parser">demo</a>.)</dd>
49    <dt id=module-whatpm-html-serializer><a href="Whatpm/HTML/Serializer.html"><code>Whatpm::HTML::Serializer</code></a></dt>
50      <dd>An implementation of HTML5 fragment serialization algorithm.
51      (See also <a href="#demo-html-parser">demo</a>.)</dd>
52    <dt><a href="Whatpm/HTMLTable.html"><code>Whatpm::HTMLTable</code></a></dt>
53      <dd>An implementation of the HTML5 table algorithm.  It can be
54      used to extract a table structure from a DOM <code>table</code>
55      element node.  (See also <a href="#demo-html-table">demo</a>.)</dd>
56    </dl>
57    
58    <p id=modules-xml>The module for <i>tentative</i> XML support is as follow:
59    <dl>
60    <dt><a href="Whatpm/XMLSerializer.html"><code>Whatpm::XMLSerializer</code></a></dt>
61      <dd>A simple XML serializer.</dd>
62    </dl>
63    
64    <p><i>Real</i> XML parser and serializer are currently not available yet.
65    
66    <p id=modules-cc>The module for conformance checking of a DOM tree (i.e.
67    a in-memory representation of an HTML or XML document) is as follows:
68    <dl>
69    
70    <dt><a href="Whatpm/ContentChecker.html"><code>Whatpm::ContentChecker</code></a></dt>
71    
72      <dd>A DOM5 HTML (in-memory representation of a document) conformance
73    checker with a partial support for Atom 1.0.  (See also <a
74    href="#demo-html-parser">demo</a> and <a
75    href="#app-webhacc">application</a>.)
76    
77    </dl>
78    
79    <p>Currently, conformance checking of HTML/XHTML and Atom documents
80    is supported.
81    
82    <p>For these modules, a DOM implementation that supports the manakai's
83    Perl binding<!-- @@ TODO: ref --> of DOM is necessary to represent a
84    document in memory.  The <a
85    href="http://suika.fam.cx/www/manakai-core/doc/web/">manakai-core</a>
86    package contains such an implementation,
87    <code>Message::DOM::Implementation</code><!-- @@ TODO: ref -->, but it
88    should also be possible to use any other implementation that supports
89    the binding.
