in thread Array / Hash Confusion!

thanks for your reply. I understand I need to store the result in a scalar and thanks for your suggested code, which I've seen works in my env.

it clearly works for "$data->{title}"; as this is a single result, but when "$data->{genres}"; this returns ARRAY(gobblydegook) as expected.

how do I effectively test if a result is an array or not, and then jump into it? or should I be converting this into a hash and trying to look at key/value combinations?

    ref is handy: 
    foreach my $key (keys %$data)
{
  my $thing = $data->{$key};
  if (ref $thing  eq 'HASH')
  {
    useThingAsHashRef($thing);
  }elsif (ref $thing eq 'ARRAY')
  {
    useThingAsArray($thing);
  }
}

    If you know it is an array: 
    print "$_\n" for @{ $data->{genres} };
