It sounds like you want Net::Whois. Here's an example that retrieves the contacts listed with the WHOIS server.

#! /usr/bin/perl

use strict ;
use warnings ;

use Net::Whois ;

my $domain = shift @ARGV or die "I need a domain to check!" ;

my $w = new Net::Whois::Domain $domain
  or die "Can't connect to Whois server\n" ;

unless ($w->ok) { die "No match for $domain" }
if ( my $contact_hashref = $w->contacts )
{
    foreach my $contact ( keys %$contact_hashref )
    {
        print join "\n\t", $contact, @{$contact_hashref->{$contact}} ;
        print "\n\n" ;
    }
}

Hi there, and welcome to the Monastery!
You don't really say exactly what kind of data you are looking for. So while we are waiting for you to go into further details, I'll just quickly point out two directions in which you might go:

• You have a website and want to know data about your visitors. While you could just look this up in your logfiles, you could also look at CGI which helps you to extract things like referer and username if they have to login etc. It seems to me that this is not what you want, though.
• You want to visit a website and get the contact details from the website's admins. For this you might want to look at Net::whois.

Perhaps this isn't at all what you want. In that case forgive me for taking your time and pointing you into the wrong directions.
:-)

Welcome!

I'm going to be presumptuous, and assume that you mean one of two things: having a form on your web site, which has contact information that you want to then get locally, or having a spider-like thing that extracts specific kinds of data (addresses, phone numbers, email) from many websites. If you are talking about the latter, I can't help too much, because I haven't done that sort of thing (although I could pretty easily figure out how - but I'm sure many monks around here would be better).

If it's the former:
What you need in that instance, is a CGI script (there are a few out there, but they aren't hard to write either - that's how I started on the perl journey) that takes data from the form, and, say, either drops it into a file (maybe delimited) or emails it to you? Is that what you have in mind? With the CGI module, it's a very easy sort of script to write, and I could certainly post mine, if you are interested.

If you know out how to extract addresses, phone numbers and emails from websites, then please don't tell people who ask. Unless you think that the world needs more spam.
