Recursive sums in xslt 1.0
I'm returning to a problem I asked a couple of weeks ago about node tests <http://www.biglist.com/lists/xsl-list/archives/200503/msg00088.html>. I've been working through the XSL 2.0 and XSL 1.0 suggestions proposed at the time by David Carlisle <http://www.biglist.com/lists/xsl-list/archives/200503/msg00089.html> and Wendell Piez <http://www.biglist.com/lists/xsl-list/archives/200503/msg00159.html>. I've listed the problem at the end of this e-mail.
The xslt 1.0 solution proposed was:
in xslt1 if you want to store an expression that is going to be re-evaluated you need to put it in a named template. Then you could call that so long as you replaced sum(..) with a recursive template that iterated over the nodes calculating the sum and calling your named templates.
I understand the named template, of course. I don't understand the second sentence, though. How would this work? I'm raising the question here rather than privately, because it seems like an important technique that might be useful (and difficult) for others like myself you are (now) probably more than beginners but less than experts.
The problem from my original e-mail:
The context is a financial xslt file that outputs itemised monthly reports from an unitemised year-to-date xml file. For each item in the output file, I need to do two tests: one for date and the other for some other feature (usually party [i.e. payer/payee]). This would be an example with no parameters or variables:
