Grouping is a standard XSLT problem. It's not real trivial, it usually requires a knowledge of keys, but it's not all that hard either. > * calculating things like averages, sums, min and max values is a lot > easier than in XSLT (or probably impossible XSLT) Sum, min, max are usually pretty much trivial.

If it's presentation oriented I'd keep it in the XSLT if it's business logic then a transformer might be more reasonable (or better, shove it even further towards the back end). --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
