in thread Calling nested containers with XML::Simple

Thanks! I agree that the second version is not very aesthetic whatsoever. I also found that when the containers are nested, they can be called via

$i->{snmp}{version}

i had been trying the syntax you show above with the second "->". i think that was the source of my frustration.

thanks again, your post helped very much. -c

    Whenever i use 'forcearray', i tend to loop: 
    for my $snmp (@{$i->{snmp}}) {
   for my $version (@{$snmp->{version}}) {
      print "$version\n";
   }
}

    Now, consider XML::XPath, which 'drills down' to the nodes in question: 
    use XML::XPath;

my $xp = XML::XPath->new(filename => 'filename');
my $nodeset = $xp->find('global/snmp/version');

print $_->string_value, "\n" for $nodeset->get_nodelist;

    Much nicer. :)
