  No, you must walk the tree. The semantic of what you are describing
is however extremely confuse, does it include equality of namespace
prefixes too, is the model recursive (if no then comparing element nodes
would make no sense), etc ...
  XML is not a reduced database, it has none of the features, and vice-versa.
The only kind of index you can find natively in the tree are ID associated
to elements. But all this is really common knowledge
