See Dudes these are the Node Attribute you can Read it like Other Attribute.Actually What The Problem you are getting here can you Show your code.and one more thing are you the one who is responsible for creating xml.if yes can you tell exactly for what you are looking. and it's always better to keep your xml in simple form.if you specify your requirement.may be we can simplify.your xml so it's easy to parse for you.
Thanx
