I can't actually test this script I've just written because my web-server is currently broken, but hopefully it will give you an idea how to go about it

If you require any help what-so-ever though, do just ask the community!

php Code:

function getElementsByExtension(array $aExtensions)
{
    $szContent = file_get_contents('http://www.talkphp.com/show-off/3929-zipthings.html');
    $aElements = array();
    
    foreach ($aExtensions as $szExtension)
    {
        preg_match_all('~(?:src|href)="([^"]+\.' . $szExtension . ')"~is', $szContent, $aMatches);
        $aElements[] = $aMatches[1];
    }
    
    $pArray = (object) array('aFlat' => array());
    array_walk_recursive($aElements, create_function('&$v, $k, &$t', '$t->aFlat[] = $v;'), $pArray);
    return $pArray->aFlat;
    
}

print_r(getElementsByExtension(array('jpg', 'gif', 'css')));
