I recommend using HTML::Tree (and its associated classes, 
HTML::TreeBuilder and HTML::Element), not HTML::Parser directly.

Once you've got HTML::Tree installed, look at the HTML::Element 
documentation, specifically at the look_down() method.  That's one that 
I tend to use a lot.  Also extract_links().
