Namespaces Heh, namespaces are a real pain, in fact that is why we were having so much trouble with our project because each document had like 10 different namespaces. The trouble with doing it in javascript was that it seemed firefox didn't need the namespace tag I believe, but IE did. So that is why I switched over to doing our parsing in PHP and stripping out the namespaces with the domdocument library which handled them better. Usually up in the top of a document is a listing of the namespaces and an url associated with them if you need to call a namespace node that is usually the url you use to define it. But we haven't done much with namespaces in JS lately. Hope that any of that helps.
