There are quite a few XPath APIs around now that are confusingly similar, it
would help if you told us which one you were using.

Why do you write "/*[name()='type']" rather than "/@type"?

Your terminology is way out (there is no such thing as an attribute element,
I think you mean an attribute node). But I can't see any reason why the
above expression shouldn't work just because the current node is an
attribute: attributes have ancestors jsut as elements do.
