Probably all about the same, under the covers.
Though, the '//' notation is woefully inefficient, simply
because it has to search the entire depth of the document
looking for a <foo> followed by a <bar>.
When possible, try to avoid the // notation, regardless of
the method or XPath engine you're using.
