An XPATH expression always identifies a nodeset (in XML speak) and the
examples I showed are AFAIK valid XPATH expressions. You can match
against element names, element contents and attribute contents with the
restricted subset I have proposed. Full XPATH allows you to do much more
fancy selection of nodesets. But at the end, it all boils down to
selecting nodeset when using XPATH, so I fail to understand your
concern.
