use HTML::TreeBuilder::XPath with htmltreexpather.pl / xpather.pl / examples(for tree-xpath and others)/walkthroughs/tutorials ...
Write something like use HTML::TreeBuilder::XPath;
my $tree = HTML::TreeBuilder::XPath->new;
$tree->parse_content( $content );
my @headers = $tree->findnodes( q{ //table[@class='HeaderFrame' ] } )
->shift ## get first one
->findvalues( q{ .//td[@class='HeaderTitle'] } );
print "@headers\n";
Or even all in one xpath expression
my @headers = $tree->findvalues( q{
(
//table[ @class = 'HeaderFrame' ]
)[1]
//td[ @class = 'HeaderTitle' ]
} );

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.
