I'm having trouble with using Perl to parse an HTML file I have, where I'm trying to grab all <a> and <div> tags if the link or text content matches a certain format (I use a regex for this). However, WWW::Mechanize can only find links (<a> tags), not <div> tags, so that doesn't work. I've tried learning HTML::TreeBuilder but it seems that my brain doesn't understand the documentation very well for some reason. I'm wondering if you chaps can either direct me to a better, cleaner Perl module that can extract all tags and let me analyze their attributes/text, or help me with my problem with HTML::TreeBuilder? My problem is that with, for example, http://search.cpan.org/~cjm/HTML-Tree-5.03/lib/HTML/Element.pm#find_by_tag_name, I have no idea what $h is, or where it's coming from. It seems - to me - the documentation for TreeBuilder and Element use variables without explaining what they are explicitly, and this hurts my brain. Some help would be wonderful, as I need to finish this project by the end of the week for my job, and I'm not sure what to do or why I'm not understanding this.

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).
