RE: XPath to match attribute with multiple values...?

In 2.0 if you have a schema that describes the attribute as list-valued then

  contains(@categories, "business")

will do the right thing.

If you don't have a schema, then

  contains(tokenize(@categories, '\s'), "business")

will do the right thing.

With 1.0, it's much harder.
