One of the implementers may correct me, but I'm not sure if it is so much heavier the *[ there is in some sence processing all the nodes anyway even if it is hidden inside an XPath rather than explictly using templates. If you do want something callable as an XPath function then alternatives are position() or count() with the exact expression depending on quite what your document structure is, but for instance foo{count(preceding::*)} might do what you want (You could use a key to pre-compute all of them to save re-calculating, perhaps) David _____________________________________________________________________ This message has been checked for all known viruses by Star Internet delivered through the MessageLabs Virus Control Centre.
