Check the follwoing it may helps you

function simplexml_get_node_value($sxml_obj, $query)
{
      $nodes = explode("->", $query);
      $currTree = $sxml_obj;

      foreach($nodes as $node)
      {
        $currTree = $currTree->$node;
      }
      return $currTree;
}

The usage will be  

$result = 'your xml source';
try { 
	$xml = @new SimpleXMLElement($result);
	} catch (Exception $e) { 
		echo "bad xml";
	}	

$qulification = simplexml_get_node_value($xml, 'qulification');

Hope this helps you.....
