Parse rss fra last.fm

hej,

Jeh kunne godt tænke mig at parse noget data ud fra min last.fm url.

  $user = 'MyUser';
  $api  = 'XXXXX';

  $recentTracksUrl = file_get_contents( "http://ws.audioscrobbler.com/2.0/?method=user.getrecenttracks&user=" . $user . "&limit=1&nowplaying=true&api_key=" . $api );

$xp = new domxpath($recentTracksUrl);
$titles = $xp->query("/lfm/track/name");
foreach ($titles as $node) {
    print $node->textContent . " ";
}

Men virker ikke.. kender intet til xpath..

Er kun interesseret i det første track(now playing), kunne godt tænke mig artist, name, album og medium image
Dette er data som URL returnere:
