When you wish to parse a HTML document (or a look alike) using HTML::TokeParser, and you're not quite sure how the document will be tokenized, this snippet can give you a good idea of what's going on.

To run, simply type "perl scriptname.pl url" you'll a dump on STDOUT looking like:

TYPE : D
####
0:<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
>
####
