I've used HTML::Parser twice so far, and it's not hard to use at all. On perlmonks.org, I've put up a script called delirium which uses HTML::Parser in a simplistic way. I've also written another script called lchtml which is a text filter that turns HTML tags and attributes to lower case. lchtml gives HTML::Parser a little bit more of a work out, and you'll probably find it more informative.
