Well, this particular DSSSL thing did occasionally put lists out of order, and didn't have a good way of peeking at items before or after in the list. You sometimes need to do that in setting books. > XSLT … is not a general purpose language and I would not want to > program such problems with it!!! The input data was in XML, so XSLT was the perfect language (supposedly) for the task. I think the agency responsible for generating the data spent quite a bit of money making it as hard to use as possible - it was data that was required by law to be published, but Difficult Questions might be asked of the agency if it were ever closely analyzed. So they wrapped it up in quite the worst XML format I've ever seen. I realize that these are domain-specific examples, but my experience of functional languages was of unnecessary complexity and putting rules in the way of getting results. cheers, Stewart --- Post to this mailing list talk@gtalug.org Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
