It might be difficult but I'll try anyway ;--).
At least here are a few hints:
- document size: big documents excludes most tree-oriented modules,
such as XML::Simple, XML::DOM and XML::XPath
big depends on your RAM and on the expansion factor of the module, typically
between 7 an 10
- type of XML: document-oriented XML excludes modules such as XML::Simple
and XML::SimpleObjects
those modules don't deal with mixed content
(<p>this is <b>mixed</b> content</p>),
- ease of use: although this is higly subjective XML::Simple seems to be
considered really easy to use as it completely masks the XML by loading it into
a Perl data structure (a pretty convoluted data-structure IMHO, use Data::Dumper!), tree-based modules (XML::XPath, XML::DOM, XML::Twig)
are generally easier to use than stream-based ones, although for simple data
extraction XML::PYX is very convenient,
- speed: at the moment XML::Parser is the fastest (all other modules
are based on it) but modules based on libXML should be faster soon (XML::XPath
2.0 for example). Stream-based modules are usually faster than tree-based ones,

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
