..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

This appears to be a standard web page question (is it?) where you want to 
know if someone has visited your site previously.  If so, you need to 
decide how you will know that fact.  One standard method is to store a 
cookie on the user's machine that you can check for on the next visit.  
This really isn't an XSLT problem at all.
