Hi Anonymous Monk,
Please, if I can make an assumption that since you used the module HTML::FormatText you intended to get your output in plain text not have the whole html page with all the tags in as text.
If this is what you want, then you can do like so:

use warnings;
use strict;
use HTML::TreeBuilder 5 -weak;
use HTML::FormatText;


  my $tree = HTML::TreeBuilder->new_from_url("http://www.google.com");

  my $format = HTML::FormatText->new(leftmargin=>3, rightmargin=>50);

  print $format->format($tree);

NOTE:

1. Of course, you might need the module LWP::UserAgent, to get your html file, if you don't have html file stored.
2. Please, note the usage of the module HTML::TreeBuilder, if you have your html file, you might use a different method.
3. However, if you are using a linux OS, you can also see lynx like so: lynx -dump http://www.google.com

I hope this helps. graff was right on the question he asked about the clarity of what you wanted done.
