Hi Jeffrey,

> Any ideas on which answer is correct?

It depends how much you care about namespaces.

  *[not(name()='a' or name()='b')]

Gives you all the elements aside from a and b elements that are in the
default namespace in their document. I'd tend to steer clear of this
because the default namespace could be anything at all.

  [not(self::a or self::b)]

Gives you all the elements aside from a and b elements that are in no
namespace. Use this if the a and b elements that you want to ignore
don't have a namespace or if you're not using namespaces at all.

  *[not(local-name()='a' or local-name()='b')]

Gives you all the elements aside from a and b elements in any
namespace. Use this if you want to ignore all a and b elements no
matter what namespace they're in.

Cheers,

Jeni
