Since XSLT is side-effect free, all iterations of a loop are
conceptually done at the same time. So there no way of finding the
node wich is about to be processed :-)

But there is a way to find the following node in document order from
the context node list:

Before invoking for-each, save the sorted node-set in a variable
(let's call it $var).  Then invoke <for-each select="$var">.
Inside the for-each loop, the next node in document order is
$var[position()+1].

PS: at last, found a question I could answer :-)
