This is the equivalent of the classic "sum of price
times quantity for all items". Solutions include:

(a) write a recursive named template
(b) (Saxon extension) saxon:sum(//item, saxon:expression("@price * @qty"))
(c) (XSLT 2.0, Saxon 8) sum(for $i in //item return $i/@price * $i/@qty) 
(c2) (next Saxon release) sum(//item/(@price * @qty))
(d) Dimitre's FXSL library (fxsl.sourceforge.net)
(e) create a temporary tree containing the values you want to sum, then use
sum(xx:node-set($temp/values))

In your case, replace "price * quantity" with "translate(., ',', '')".
