Thanks Michael, that works great.  I just needed a fresh pair of eyes to

as test


I suspect you should simply substitute "starts-with" for
"substring-before".
If X starts with Y, then substring-before(X,Y) is a zero-length string,
which equates to false, which seems to be exactly the opposite of what
you
intended.
