Don't test on $1. Since we now know that it stays set after a successful match,
we know it is not a valid test. Test on the opertion itself, or assign the
operation itself to a scalar, aqnd test on that. Now I know why this snippet
from your original post raised a red flag for me:
> $var =~ /.*? \(.*\) (.*?) \(.*?\)/;
I saw it, and wondered "Well, what is he doing with it?". The matching function
is intended to return a true value on success, and that value is assigned to your
blandly-named $var, yet it is never used.
Try instead:
if ($var =~ /.*? \(.*\) (.*?) \(.*?\)/;) ) {
# anything referring to regex variables should come within this scope.
}
