Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

This stuff really does my head in :-), can anyone help please?

If I can access each of the values in a multi-dimensional array like this:

$xml->{event}->[0]->{venue_code}
$xml->{event}->[1]->{venue_code}
$xml->{event}->[2]->{venue_code}

How can I loop through all the array values, rather than specifying an index for each one?

I.e. something like this.

foreach my $event ($xml->{event}) {
  print "$event->{venue_code}<br/>"; #this doesnt work
  print "$event->[0]->{venue_code}<br/>"; #this works
}

Thanks, Tom

    You simply forgot to dereference the array:

                       ||             |
                   vv             v
foreach my $event (@{$xml->{event}}) {
  print "$event->{venue_code}<br/>";
}
