XSLT is a declarative language, not a procedural language.
You need to forget all about procedural methods.

There are certainly ways to do this. But don't think in terms
of for-each: there are usually better ways of performing an
operation on a set of data. In XSLT, for-each is only used when
you want to process some set of values out of normal document
sequence, or if you want to process them on several occasions,
or if you want to change their sort order. In normal document
sequence there is an apply-templates operation which causes
specified nodes to be processed.

Look at the XSLT FAQ for "named templates":
