Recurse XML, ZIP problem

Hej allesammen!

Jeg er i gang med at lave en slags ZIP handler. Problemet er at specificere hvilke filer jeg vil extracte i en .xml fil, som jeg ikke kan finde ud af at recurse ordentligt. Den kan ikke nå 3. grads noder.
En del af min PHP klasse:

 /*
          * extract
          * 
          * Extract the project to a given destination.
          * First read the info.xml then unzip files
          * 
          * @access public
          * @param string $destination
          * @return bool
          */
         public function extract($destination)
         {
             $fip = new ZipArchive;
             if($fip->open($this->filename) !== true)
                 return false;
             
             $infoFile = $fip->getFromName("project/info.xml");
             if(!$infoFile)
                 return false;
             
             if(!$infoXML = new SimpleXMLElement($infoFile))
                 return false;
