I have a small problem in my XSL file when converting string to a number. This is how it’s being done:
Where, for example, stringValue can be "0.5" in US region or "0,5" in some European regions.
While the conversion from "0.5" works great, a conversion from "0,5" results in failure and a NaN result.
Does anybody know of a way of handling number conversion in XSL in a universal way that is independent from regional settings and would work for both "0.5" and "0,5"?
