Thanks Rob. I think ForceArray is what I need but I can't come up
with the right setting. If I set 'ForceArray => 1', everything seems
to be forced into an array but I don't want to loop with foreach for
every value I want to retrieve. I'd like to force only
$parsed_response->{Label}->{Image} into an array but I can't find the
correct setting for ForceArray.
