Mark,

At 03:52 PM 11/10/2008, I wrote:

In order to exclude Red and Blue, use a predicate:

//colour[not(.='Red' or 'Blue')]

Oops: this should of course be

//colour[not(.='Red' or .='Blue')]

and adjust the rest accordingly.

Sadly, ".='Red' or 'Blue'" will always be true, so //colour[not(.='Red' or 'Blue')] will always be empty. This could be a difficult bug to trace.

Cheers,
Wendell
