You can't.

Some processors have extension functions that allow this (saxon:assign
being one of the guilty parties) but the design of XSLT is totally
influenced by the fact that it is a side effect free language.

It's not that imperative programming is necessarily evil, but if you
want to program in that style it makes more sense to use a language that
has assignment statements (omnimark, perl, ....) rather than trying to
twist a language that does not.

If you said what you were trying to do at a higher level, perhaps
someone may suggest how it would be done more naturally in XSLT.
