Re: Counting elements with count() and position()

Thanks Jeni,

That reply was much more than I had hoped for.

One problem - 4 solutions.

I do get a buzz working at home through your 'StarTrek' counting examples
in Begining XSLT then posting a question and getting a reply 10 mins.
later from the author herself.

I look forward to completing this book and moving onto the one beside it
'XSLT and XPATH On The Edge'.

Many thanks,
Best regards
Rudi.
