Regarding NameNodeMap!!!

Hi !!

Here's my query!!! ........Can somebody help me out on this.......???

In DOM specification, an element's NamedNodeMap contains its attribute nodes. In DOM level 1,we use setNamedItem to retrieve a node from NamedNodeMap by its name. In DOM level 2 the setNamedItemNS method is used..., 

I wanted to know ....What should be the lookup key used to retrieve from NamedNodeMap? Is it qualifiedName(two-part name containing prefix and localName) or two-part name containing localName and namespaceURI?


thanx in advance,

regards
