 From this posting of yours it's not clear to me what issue you have. 
Any XML or HTML parser that rips a document apart and builds a DOM of 
some kind will create a nested, strictly hierarchical tree structure. 
The only thing that may seem odd is that XPath queries beginning with 
"//" search through the complete document regardless of the node you 
invoke the method on.
