I wouldn't want to place a bet on which approach will be faster, but I rather doubt the difference would be significant. In earlier Saxon releases navigating the ancestor axis could be slow in trees with a very wide fan-out, but that problem was solved a while ago. Michael Kay http://www.saxonica.com/
