You've got to stop thinking in terms of updating variables as you go along,
and thing in terms of a function.

With Saxon it's easy, 
saxon:sum(preceding::text(), saxon:expression('string-length(.)');

With standard XSLT it's a bit more work: you need a recursive template that
calculates the total string-length of a node-set by finding the
strgin-length of the first node, and adding the total of the remaining
nodes, which you get by calling yourself recursively.
