I have a module that I am using that returns a multi-dimensional hash
My script gets data returned as
use strict;
use warnings
my $returnedData = $findVars->get();
I can access the data individually like
$returnedData->{..}{..};
Of Course replace the
.. with a string, number, or variable of choice
What I am wondering is how do I go about doing a foreach(keys ...) on something that
complex
If I try to do a foreach(keys $returnedData) I of course get an error telling me that I cant do this because $returnedData is a scalar, not a hash.
Any wisdom?
