ajax output

[ragtek]

How workts the part with the ajax output?
I have this code:

function del_link(linkid){
	var link = linkid;
	
	dellink = new vB_AJAX_Handler(true);

	dellink.onreadystatechange(handle_dellink);
	dellink.send('linkliste.php?' + SESSIONURL + 'do=del', 'linkid=' + link);
	return false;
}

function handle_dellink(){
	
	if (dellink.handler.readyState == 4 && dellink.handler.status == 200)
	{
		if (dellink.handler.responseXML)
		{
			var error = me.xml_sender.fetch_data(fetch_tags(dellink.handler.responseXML, 'error')[0]);
				
			if (error)
			{
				alert(error);
			}
			else
			{
				var ausgabe = dellink.fetch_data(fetch_tags(dellink.handler.responseXML, 'response')[0]);
				fetch_object('danieltest').innerHTML = ausgabe;
			}
			alert(dellink.handler.responseText);
		}
	}
}

PHP Code:

if ($_REQUEST['do']=='del')
{
    if (!$show['admincplink'])
    {
        print_no_permission();
    }
    
     $linkid =& $vbulletin->input->clean_gpc('p', 'linkid', TYPE_INT);
     $db->query_write("DELETE FROM " . TABLE_PREFIX . "linklist WHERE linklistid = " . $vbulletin->GPC['linkid']);
         require_once(DIR . '/includes/class_xml.php');
         $xml = new vB_AJAX_XML_Builder($vbulletin, 'text/xml');
     
     
     if ($db->affected_rows())
        {
            $xml->add_tag('response', 'gel?scht');
        }
        else 
        {
            $xml->add_tag('error', 'fehler beim l?schen');
        }
        $xml->print_xml();
} 


This code deletes an link(this part works)
Now i want to write "gel?scht" into the danieltest - div
But heres now a error::

dellink.xml_sender has no properties
var error = dellink.xml_sender.fetch_data(fetch_tags(dellink.h andler.responseXML, 'error')[0]);

Can somebody help me?
