You don't. XSLT is a functional language, not a procedural one. "++i" is
impossible because of XSLT's side-effect-free nature -- variable "i" is not a
pointer to a mutable section of memory; it is the name of an object in the
XPath/XSLT data model.

I would need more info about what you're doing in order to provide a better 
answer, but as Thomas Passin pointed out, if you are processing a node-set,
you can use position() in the template(s) that match the nodes in that set.
