The attribute Axis

The attribute axis selects an attribute node contained by the context node. For example, the XPointer /descendant::SPOUSE/attribute::IDREF selects all IDREF attributes of all SPOUSE elements in the document. The attribute axis can be abbreviated by an @ sign. Thus //SPOUSE/@IDREF selects all IDREF attributes of all SPOUSE elements in the document. @* is a general abbreviation for an attribute with any name. Thus //SPOUSE/@* indicates all attributes of all SPOUSE elements.

For another example, to find all PERSON elements in the document http://www.theharolds.com/genealogy.xml whose FATHER attribute is Jean Francois Bellau (ID p2), you could write //PERSON[@FATHER="p2"].
