Hi all.
Can anybody tell me the fastest way, how to test, if variable contains some
text or number?
For now, i am using test "string-length($variable)=0", but seems not to be the
fastest.
Somebody tells me to use test "$variable", but with my XalanC, it seems to be
true everytime.
Thanks.
PS. variable can't contain nodes, it may contains only alphabetics or numbers
and whitespaces.
