David,

Why should this take a long time? Isn't this the same as

*[not(name() = name(preceding-sibling::*[last()]))]

You are correct -- a bug in my code. Given a node-set argument, name() will operate on the first node in the set in document order (here, preceding-sibling::*[last()]), which therefore won't de-duplicate properly.

So it won't take a long time, and it won't work either.

The key-based approach, or Ken's, will work however.

Thanks for your vigilance, David.

Cheers,
Wendell
