Well the XPath 2.0 solution is
sum(for $i in preceding-sibling::text() return string-length($i))
For XSLT 1.0 it's much more difficult, it's the classic problem of
summing a calculated value over a node-set. There are several workable
solutions:
- Construct a result tree fragment containing the computed values, then
use the sum() and xx:node-set() functions to do the summation.
- Use a recursive template
- Use Dimitre's FXSL library.
