[Pdx-pm] HTML::Parser help

[Ovid]

Hi Thomas,

HTML::Parser is great, but not everyone can wrap their head around it
that easily.  Many prefer a procedural approach as this better maps to
how we're used to getting things done.  If that is appealing at all,
you may find HTML::TokeParser::Simple of use.  It's ridiculously easy
to use.  For example, to only print out the "visible" text in an HTML
file:

  my $parser = HTML::TokeParser::Simple->new($html_file);
  while (my $token = $parser->get_token) {
    print $token->as_is if $token->is_text;
  }

There are several more comprehensive examples in the distribution.  Of
course, while I admit to being biased, I do find it easier to use than
HTML::Parser.

Cheers,
Ovid
