[xsl] Re: how to create sub-totals and carry-overs

["Dimitre Novatchev" <dnovatchev@xxxxxxxxx>]

For a linear solution for obtaining incremental results over a list
(e.g. running totals, etc.) do have a look at the functions scanl() and
scanl1() from the FXSL functional programming library. they are located
in the file scanl.xsl


Hope this helped.

Cheers,
Dimitre Novatchev.
