AJAX with ASP - responseText works, responseXML doesn't

Hi all,
just starting with AJAX and come up against the following problem. I created a simple script reading a plain XML file and it worked fine.

However when I reproduced the same XML using ASP, whilst responseText reproduced it fine, a reference to the XML DOM using reponseXML didn't seem to have any content.

As far as I know the server is .NET

Can anyone point me in the right direction?

many thanks

Sorted it. I just needed to put

<%
response.ContentType = "text/xml"
%>

in my asp file. Otherwise the response header is set to Content-type: "text/html" which I guess is what the problem was.

WORD OF WARNING
IE does not support responseXML!!!!!!!!!!

I had a similar issue with IE you actually have to enter the information into a div tag use DOM on the div tag and then delete the info.

Here is an example I did

//function responseReports()
//{
// try
// {
// if (xmlHttpForms.readyState==4 || xmlHttpForms.readyState=="complete")
// {
// if (!finished)
// {
// var xmlDoc;
// alert(xmlHttpForms.responseText);
// if (window.ActiveXObject)
// {
// xmlDoc = convertMS(xmlHttpForms.responseText);
// alert("done");
// }
// else if (document.implementation && document.implementation.createDocument)
// {
// //alert("Other Browser");
// xmlDoc = xmlHttpForms.responseXML;
// //In case to be the internet explorer
// }
//
// else
// {
// //If the browser doesnt support xml
// alert('Your browser can\'t handle this script');
// return;
// }
// var table = document.getElementById("tbSelReports");
// var divTag = handleReportData(xmlDoc);
// alert("done");
// table.appendChild(divTag);
// finished=true;
// alert("done");
// }
// }
// }
// catch(e)
// {alert(e.message);}
//}

function convertMS(responseTxt)
{
alert(responseTxt);
try
{
//Create a xml tag in run time
var testandoAppend = document.createElement('xml');

//Put the requester.responseText in the innerHTML of the xml tag
testandoAppend.setAttribute('innerHTML',responseTxt);
//Set the xml tag's id to _formjAjaxRetornoXML
testandoAppend.setAttribute('id','_formjAjaxRetornoXML');
//Add the created tag to the page context
document.body.appendChild(testandoAppend);

//Now we can get the xml tag and put it on a var
xmlDoc = document.getElementById('_formjAjaxRetornoXML');
//So we have a valid xml we can remove the xml tag
document.body.removeChild(document.getElementById('_formjAjaxRetornoXML'));
return xmlDoc;
}
catch(e){alert(e.message);}
}
