in reply to Accessing and array of hashes

$test_data in info::test is an array reference, not a hash reference. You can't dereference it as a hash. What do you want to extract? The name of the first element?
print $test_data->[0]{name};

Or, the names of all the elements?

print join ', ', map $_->{name}, @$test_data;

    I need to access all of them, and it might be more them one block of the same key, so if I print:
    print $print_data->[0]{name}
    it prints 45 occurrences but with the same value.
      Need to use a loop:
      foreach my $detail (@{$test_data}){ my $name = $detail->{name}; print "$name\n"; }
