RE: [xsl] XSLT vs javascript performance

["Michael Kay" <mike@xxxxxxxxxxxx>]

When comparing the performance of a high-level language (XSLT) to a
lower-level language (Javascript), the first rule is that the ratio depends
more than anything else on the skill of the programmer writing in the
lower-level language. Unless you factor that as a variable into your
comparison, the results are fairly meaningless.
