Parsing JSON string with Perl when the elements name are unknown

[liadmz]

Hi,

I would like to parse JSON string using perl.
which is very trivial up until the moment the elements name are unknown.

normally I would use:

my @elem= @{ $decoded->{'elements'} };
foreach my $el ( @elem) {
  print $el->{"attr"} . "\n";
}

How can I do the same assuming I have no knowledge on the elements names (I'm sure there has to be a way to access it using the index, I just could not find it)

THANKS!
