DOMi convert array to xml

Question

Has anyone used the new DOMi?

I can't get this to work:

function createXML($proparray)
 {
 include("domi.class.php"); 
     $DOMi = new DOMi('root');  
     $DOMi->AttachToXML($proparray, 'property');
    $DOMi->Render(array(),'RENDER_XML');
 }
}

$proparray is an array: a numeric array holding multiple multidimensional associative arrays

like $proparray[0] => array('field1' => 'data1', 'field2' => array('subfield1' => 'subfielddata1'));
