in thread Array to hash converstion

$correction = $data_pair->{value} if($data_pair->{key} eq 'correct');
how to store the value in $correction only if the $data_pair->{value} is not empty.

    check to see if it is empty (whatever that means :D)
    $correction = $data_pair->{value} if exists $data_pair->{value} and # could be undef defined $data_pair->{value} and # at least "" length $data_pair->{value} and # has length $data_pair->{value} and # has true value $data_pair->{key} eq 'correct';
