You can use this Perl module LWP::UserAgent to get the data from the other site and then parse the result to extract your data.
use LWP::UserAgent;
$ua = new LWP::UserAgent;
$ua->agent("$0/0.1 " . $ua->agent);
# $ua->agent("Mozilla/8.0")
$req = new HTTP::Request 'GET'=> 'http://www.sn.no/libwww-perl';
$req->header('Accept' => 'text/html');
# send request
$res = $ua->request($req);
# check the outcome
if ($res->is_success) {
print $res->content;
} else {
print "Error: " . $res->status_line . "\n";
}
