I found an example on the net that works. (I renumbered the source to shorten response).
However can someone post an example where you don't have to go through the intermediate step of reading from a file? Instead of $parser->parse_file($file) do a $parser->parse_text($html). Where $html comes from a LWP::Simple get call and parse_text($html) I made up.
Are there any alternatives to using parse_text?

    1   #!/usr/bin/perl -w
    2   package Example;
    3   use strict;
    4   
    5   require HTML::Parser;
    6   
    7   @Example::ISA = qw(HTML::Parser);
    8   my $parser = Example->new;
    9   $parser->parse_file('index.html');
   10   
   11   print $parser->{TEXT};
   12   
   13   sub text
   14    {
   15      my ($self,$text) = @_;
   16      $self->{TEXT} .= $text;
   17    }
