Subject Re: XSLT PostProcessor - how does it work?
Date Thu, 17 Feb 2011 13:00:38 GMT
I do not know how xpath2.0 coul help, becouse xpath is about extracting info
from xml, not creating new one. if i could write XQUERY instead of the xpath
expression, that could help! maybee saxon suports it transparently, i will
try that later!

thx for advice,  i will report my findings.
