check (e.g. grep) for lines, which contain 'mailto:' (be more specific if you like to; match the 'href' ...);
use Regexp::Common together with Regexp::Common::Email::Address to identify the mail address in matching lines

PS: Don't remove your original question here.

My experience in perl is going on about 3 weeks...so some of what you are saying is greek to me. Can you provide an example of how you would do it? The source file to pull the information from has the tag as follows:

showTollfree(1010)
// -->
'/script'
Fax:  (301)931-1285 
'br''a
href='mailto:KHargrove@servpro1010.com'>KHargrove@servpro1010.com'/a'

'/td'

I'm sorry to have to be wet nursed through this...but I have learned a ton of stuff over the last few weeks...I feel like my brain is going to explode!

Well, first install these two modules (and their unresolved dependencies if there are any):

• Regexp::Common
• Regexp::Common::Email::Address

Then you can do something like this (Quickshot, untested):

#!/usr/bin/perl
use strict;
use warnings;
use Regexp::Common qw(Email::Address);
use Email::Address;

my $filename = 'file_to_parse.dat';

open my $rh, '<', $filename or die "$filename: $!";

# Requirement: href=, mailto: and the mailaddress must be in the same 
+line!

my @addresses = 
  map { m/mailto:($RE{Email}{Address})/o; $1 } 
  grep { m/href=.+?mailto:/ } 
  <$rh>
;

close $rh;

{
  local $, = local $\ = "\n";
  print @addresses;
}

__END__

Also, older HTML allowed you to not quote the information after the equal sign in some circumstances.

Newer HTML too; it is only XHTML that makes quoting attribute values mandatory in all circumstances.

Since email addresses will include an @ character, the attributes are mandatory in this case.

That said, it isn't as if nobody ever breaks the rules, so it is generally a good idea to write code that can cope (unless you know that the incoming data won't have that problem).

#!/usr/bin/perl

use strict;
use warnings;
use LWP::UserAgent;
use HTML::TokeParser;
use URI;

my $ua = LWP::UserAgent->new;
$ua->timeout(10);
my $root_uri = 'http://example.com/';
my $response = $ua->get($root_uri);
if ($response->is_success) {
    my $html = $response->decoded_content;
    my $p = HTML::TokeParser->new( \$html );
    while (my $tag = $p->get_tag('a')) {
       my $href = $tag->[1]{href};
       next unless $href;
       my $uri = URI->new_abs( $href, $root_uri );
       next unless ($uri->scheme eq 'mailto');
       print $uri->to, "\n";
    }
} else {
    die $response->status_line;
}
