Hi,
I am trying to loop through nested repeated elements in my config file but I am unable to find the number of nested elements:
Sample XML File:
<opt>
  <person firstname="Joe" lastname="Smith">
     <email>joe@smith.com</email>
     <email>jsmith@yahoo.com</email>
  </person>
  <person firstname="Bob" lastname="Smith">
     <email>bob@smith.com</email>
  </person>
</opt>

Perl Code:
use XML::Simple;
use strict;
use Data::Dumper;
my $config = XMLin("testFile.xml",forcearray => ['person','email']);
my @persons = $config->{person};
print "Size:".@persons;

[download]
On running I always get the size as 1. I think the way I am trying to get the size is wrong because in order to get the person blocks I need to do $config->{person}->[0] etc. instead of $config->{person}[0]. I admit I have not used hashes earlier but I did try keys function on $config->{person} which gives "Type of arg 1 to keys must be hash (not hash element)" error. Could anyone please tell me the right way to loop through the elements?
Regards,
Ranjan
