Hi,
I have specific business requirement where I need to transform the
source tree bottom up. The reason being certain attribute of the
parent node gets its value from a similarly caluclated child node. i.e
I need to calculate a derived attribute of a child node before I can
calculate the parent node's attribtue.

Is such a requirement be addressed using XSL? If yes any pointers will
be very helpful.

Thanks,
Raghu
