Here is a simple example I use to grab the currently playing song on KCRW.com and display it on the console window as well as write it to a playlists file

#!perl

use strict;
use LWP::Simple;

my $url = 'http://www.kcrw.com/';
my $sleep_time = 120;
my ($sec, $min, $hour, $mday, $mon, $year, $wday, $yday, $isdst) = loc
+altime;
my $playlist = 'playlist.txt';

# What do you want to find out about
my $start = "<a href=\"javascript:KCRWmusicAlbum.*\">";
my $stop1 = "<\/a> by <a href=\"javascript:KCRWmusicArtist.*\">";
my $stop2 = "<\/a> at";
my @playlist;
my $last_song;

while ($hour < 14) {  # only until 2p central
  die "Couldn't get $url" unless (my $content = get $url);
  # search the $content for the $kw
  $content =~ m/$start(.*)$stop1(.*)$stop2/i;
  if ($1 ne $last_song) {
    my %song = ('SONG' => $1, 'SINGER' => $2);
    push(@playlist, \%song);
    $last_song = $1;
    print "Now playing: '$1' by $2\n";
    open PL, ">>$playlist" or die "Cannot open $playlist: $!";
    print PL "$1|$2\n";
    close PL;
  }
  sleep $sleep_time;
}
