I've formulated sample files to illustrate the
problem:
************************************************

****************************************************
I am trying to implement multilple
transformation/node-set(). Because after first
transformation, I get complex fo:block 's. So I doubt
this technique will help in my case.
Thanks & Regards,
Raj
PS: Thanks to Mukul(you got my problem.)Details are
given above.
