If the returned XML deos not have dclarations for the ds and z namespace
prefixes then it's not XML.

In any case you'd be better off using XPath rather than DOM select methods. In
IE you set the namespace and prefix first:
objDom.setproperty("SelectionLanguage", "XPath");
objDom.setProperty("SelectionNamespaces", "xmlns:ds='<uri goes here>'
xmlns:z='<uri goes here>'");
var sXPath = "/*/z:row"; //This is probably wrong but I haven't seen your XML
var colNodes = objDom.selectNodes(sXPath);

You'll have to look at the comparable methoid for Mozilla XPath usage.
As I said using Sarissa relieves you of some of these headaches.
