javascript - getElementsByTagname Problem

[ragtek]

hi
i have a form which comes with an ajax response and looks like this:

<?xml version="1.0" encoding="windows-1252"?>

<template><![CDATA[<form><input type="text" name="bildname"><input type="submit">]]></template>

<bildid>3906</bildid>

now the js code for checking looks like this:

	showform:function(ajax){
		
		var error = ajax.responseXML.getElementsByTagName("error")[0];
		if (error){
			alert(ajax.responseXML.getElementsByTagName("error")[0].firstChild.nodeValue);
		}
		else {
			var bildid = ajax.responseXML.getElementsByTagName("bildid")[0].firstChild.nodeValue;
			fetch_object("formcontainer_"+bildid).innerHTML =ajax.responseXML.getElementsByTagName("template")[0].firstChild.nodeValue;
		}
	}

i'm getting this error:

ajax.responseXML.getElementsByTagName("bildid")[0] has no properties
[Break on this error] var bildid = ajax.responseXML.getElementsByTagName("bildid")[0].firstChild.no...

but as you see, it is in the response
