well, what do you mean by "I have an array refs" ? how do you contain them ?

the following foreach block example extracts State value for a single ref :

my $ref = [
        {
                'State' => 'Maine',
                        'Town' => 'Portland'
        },
        {
                'State' => 'New Hampshire',
                'Town' => 'Concord'
        }
];

foreach ( @{$ref} )
{
        print $_->{State}."\n";
}

so to use it on all your refs, you'll need to run this foreach loop on each one of your refs.

HTH.
