Check for existence of elements in a Hashrefby quicoju (Initiate)
|on May 03, 2013 at 23:23 UTC||Need Help??|
quicoju has asked for the
wisdom of the Perl Monks concerning the following question:
I'm trying to check that a number of elements exist in a Hashref. Instead of checking for one element at a time, I'd like to do the check them all in one pass.
The following code is what I've tried so far, but I'm getting some unexpected behavior. It looks that it only check s for the last element in the slice
Is this the correct way to check for element existence?
Please enlighten me ...Thanks
