How can you tell if a variable exists (or rather does not exist), without
erroring out of the stylesheet.
For example:
I am using the SAXON servlet to present HTML to the user. I am passing in
the parameters from doPost to the stylesheet. If the parameters exist, all
is well. But when a parameter does not exist, and is not passed to the
stylesheet, I just get an exception. How do I prevent that?
TIA,
