search and retrieve the text between the open and close tag of any user specified type

HTML::TokeParser (alt.) or it's ::Simple (alt.) offspring should help here.

nice little loop to go through all the user specified ones

It would be a simple foreach (param('tag')) if you dropped the numbered suffixes, but otherwise you could use [grep] to filter out the unwanted params.

use CGI qw/ :standard /;
use Data::Dumper;
use HTML::TokeParser;

my $file = param('file');

  # user defined tags.
my @tags = grep /\Atag\d+\z/, param;

my %text;

foreach my $tag_name ( map param($_), @tags ) {

    # Is there a better way to rewind the parser?
  my $html = HTML::TokeParser->new($file)
    or die "Cannot parse $file";

  print "$tag_name\n";

  while ( my $tag = $html->get_tag($tag_name) ) {
    $text{$tag_name} = $html->get_trimmed_text("/$tag_name");
  }

}

print Data::Dumper->Dump( [ \%text ], [qw( text )] );

Something to be wary of, however, is if there isn't a closing tag, get_trimmed_text will return everything until the end of the document; which could suck royally if all you want to search are <meta> tags.
