           <ff:size>750319</ff:size>
       </ff:ebook>
   </entry>

  <entry>
      ....

My phpcode looks like this:

$data = simplexml_load_string($xmlstr);
$result = array();
foreach ( $data->children() as $entries ) {
    $item = array();
    foreach($entries->children() as $key => $entry) {
        $item[$key] = $entry;
    }

   foreach($entries->children('ff', true) as $key => $entry) {
        switch ($key) {
            case 'actor':
                // what do i write here to get the children?
            break;
            case 'ebook':
                // what do i write here to get the children?
            break;
            default:
                $item[$key] = $entry;
            break;
        }
    }
    $result[] = $item;
}

I've tried with both children() and attributes() but still having a hard time getting the child elements of both actor and ebook.

Any help is much appreciated!

works here: http://ideone.com/GfmqQh

foreach($entries->children('ff', true) as $key => $entry) {
    switch ($key) {
        case 'actor':
            // what do i write here to get the children?
            var_dump($entry->children('ff', true)->name);
            //if case you like get attributes... $entry->attributes(), return array of attributes
            echo "actor
";
        break;
        case 'ebook':
            // what do i write here to get the children?
            echo "ebook
";
        break;
        default:
            echo "$key default
";
            $item[$key] = $entry;
        break;
    }
}
$result[] = $item;
