Re:Re:Using condition expression with an empty string variable


Hi,  Jeni,

Thanks for the solution, it works.

More import to me is your nice explanation about using string() to convert
an empty node set into the empty string and then doing comparsion with the
given empty string variable.

It is a good lesson to know the basic about  difference between empty node
set and empty string.
