transportXML returns null?

Hi,

I want to load an XHTML file into DOM.  I issue Ajax.Request
and on
success do:
 var response=transport.responseXML

Response is null.  On the other hand:
  var response=transport.responseText;  // has the data.

Why is response=transport.responseXML returns null?

Here is the code:

    function display() {
       url = "http://"
+ location.hostname + port + "/fusion/
restlet/";
       url = url + "engines" + sServer;
        new Ajax.Request(url,
        {
            method:"get",
            contentType:"application/xhtml+xml",
            onSuccess: function(transport) {


                var response = transport.responseXML;    //
null ?
                //var response = transport.responseText;  //
OK

                alert("after response=" +
response);
                if (response != null) {
                alert("b=" +
response.getElementById('lastUpdate').innerHTML);  // this
never works
               }
                else
                    alert("onSuccess, responseXML is
null");
            },
            onFailure: function(){ alert("Cannot get
data from server:
" + location.host) }
        });
    }

You have to set a correct content-type (application/xml).

This is what I added to the XHTML file that I get:

<meta http-equiv="Content-Type"
content="text/xml; charset=UTF-8" />

and this:

new Ajax.Request(url,
        {
            method:"get",
            contentType:"text/xml",
            onSuccess: function(transport) {

And I still get null:                var response =
transport.responseXML;

Thanks!

I use the following code in PHP to make sure my output is
interpreted
as XML

header("Content-Type: text/xml");

and this code for ColdFusion.

<cfheader charset="utf-8"
name="Content-type"
value="text/xml">


Cheers,
       Matt
