I have been messing around with some logic on a function and have ran into a snag. I know in regexp pattern matching the script will search a string for a certain pattern. If the pattern is found the entire string containing that pattern (seperated by whitespace) is returned and not just the matched pattern.

I need a way to return just the matched pattern from the whole matched string. I cannot think of a way to seperate the pattern from it's string.

Here is an example program I have to test against my own site for example. 

#!/usr/bin/perl -w

use strict;
use LWP::Simple;

my($target, $response);

if (!$ARGV[0]) {
   print "Enter launch site! (don't forgot to include the \"http://\")
+\n";
   exit(0);
}

while (1) {
   exit(0) if(($target) && ($target eq $target));
   $target = $ARGV[0] unless($target);
   $response = get($target) || die "Cannot get page!\n";

   my @results = split(/ /, $response);
   foreach (@results) {
      if ($_ =~ m/(http\:\/\/).+/) {
         print "URL found: ".$_,"\n";
      }
   }
}

Any help is appreciated.
