RE: [xsl] Sorting By a calculated variable

["Michael Kay" <mike@xxxxxxxxxxxx>]

The variable $totale has the same value for every item in your list, so
sorting by $totale will have no effect. You need to compute the sort key for
each individual item in the list. This can be a bit tricky in XSLT 1.0
because the computation must be done within a single XPath expression. There
are various tricks for getting around the limitations this imposes. But I'm
not going to suggest code in your case because I can't see the source
document structure and your existing computation looks rather strange.
