xmlhttp (ajax) problem

Poster denne på engelsk jeg (gidder ikke oversette):

 

I'm using AJAX (xmlhttp) to validate a simple form.

 

My server side works fine. It returns this XML when validation is ok:

<?xml version="1.0" ?><secrets><error>-1</error></secrets>

 

 

Here is the method I've got for getting the response XML:

function handleHttpResponse() {
 if (http.readyState == 4) { 
 if(http.status == 200) { 
 	var errorNode = http.responseXML.getElementsByTagName("error")[0];
 	var errorTextNode = errorNode.childNodes[0]; // I get an error on this line
 	var error = errorTextNode.nodeValue;
 	document.getElementById('name').value = error; // print the error to user
   }
 }
}

 

I want to get the value of the "error" node in the XML, but I get a problem:

The method failes on the line "var errorTextNode = errorNode.childNodes[0];" with the Javascript error message: "Object required".

 

I just can't figure it out.

 

Please help!

 

How can I actually check that the "http.responseXML" receives the XML?? When I use "alert(http.responseText)" it prints out the xml ok, but if I use "alert(http.responseXML)" is just get "[object]".
