Summing numbers with comma as decimal separator in XSLT?

Question

I have an XML file where the number are comma-separated

Answer 1

I am guessing, that the value specified in a "val" attribute is a number that has comma instead of a decimal point.

Several solutions are possible:

I. XSLT 1.0

This transformation:

when applied on the originally-provided XML document:

produces the wanted result:

13.68

II. XSLT 2.0

This transformation:

when applied on the same XML document, produces the same correct result:

13.68

III. FXSL 2.x

This transformation:

when applied on the same XML document produces the same correct result:

13.68

The last solution is more flexible and can be used successfully when a more complex transformation of the values is needed before summing.
