Using my XPath library, for one.
XPath xpath = new XPath("/foo/bar/baz/@goober");
List results = xpath.applyTo( myDoc );
You're now holding a list of Attributes named 'goober', with no
convenient way to find the parent. (Which also means I can't implement
easily the XPath of "/foo/bar/baz/@goober/..", which would automagically
return the parents of all 'goober' attributes).
