It looks like that library only supports retrieving by array offset. The library is simply a magic SimpleXMLElement object wrapper for the raw XML the web service returns.

Any changes would require modifying that external lib and then updating the bundled library. Might be worthwhile creating a new issue for the other project and tracking changes there.
