xmlhttp and responseXML failing to read if CDATA section present

I am trying to read the response through responseXML and whenever the
response XML contains a CDATA section it won't parse. I've seen posts on
the web where character encoding might present some issues but I'm just a
little confused.
The response would be something very innocuous:

<result>
<code>1</code>
<details><![CDATA[test]]></details>
</result>

If the details node contains the word "test" without CDATA surrounding it,
it will parse fine.
Anyone know what's going on?

Thanks much.
Jiho

I have saved your XML example and then script it as follows

var httpRequest = new ActiveXObject('Msxml2.XMLHTTP');
httpRequest.open('GET', 'test20040327.xml', true);

httpRequest.onreadystatechange = function (evt) {
if (httpRequest.readyState == 4) {
var xmlDocument = httpRequest.responseXML;
var details = xmlDocument.getElementsByTagName('details')[0];
alert(details.firstChild.nodeType);
}
};

httpRequest.send(null);

and I do not get a parse error and the nodeType is correctly shown as 4
for CDATA section node.

I have to apologize Martin, as I found in my code a missing closing "]" for
the CDATA section. I guess I was too quick to post and/or have eyes that
deceive me. :)

Thanks for your help though.
