RE: Problems calculating the running time of an xsl s

This is because order of execution in XSLT is undefined - it's meaningless to talk of which expressions are evaluated "at the start" or "at the end" of the transformation. For example, a global variable might be evaluated at the start, or it might be evaluated on first use - or even on each use if the processor so decides. > > Is there a way to calculate the running time of an xsl script > within the script? > You can call extension functions, recognizing that the result of calling "impure" extension functions is not 100% predictable. But for most purposes, I'd suggest that measuring it externally (from the calling application) makes more sense. Regards, Michael Kay http://www.saxonica.com/ http://twitter.com/michaelhkay
