in reply to Using XML::Simple with nested arrays

If you use Data::Dumper along with XML::Simple (the dynamic duo?) you can see that, using forcearray => 1 with XML::Simple, your XML becomes this:

$VAR1 = { 'node' => { 'edge2' => { 'community' => [ 'anotherthing' ], 'loopback' => [ '10.6.21.10', '10.12.71.14' ] }, 'edge1' => { 'community' => [ 'something' ], 'loopback' => [ '172.16.254.10' ] } } };

So, I believe you want something like this:

#! /usr/bin/perl use strict ; use warnings ; use XML::Simple ; #use Data::Dumper ; my $xml = <<'EOD' ; <network> <node name="edge1"> <community>something</community> <loopback>172.16.254.10</loopback> </node> <node name="edge2"> <community>anotherthing</community> <loopback>10.6.21.10</loopback> <loopback>10.12.71.14</loopback> </node> </network> EOD my $data = XMLin( $xml, forcearray => 1 ) ; #print Dumper( $data ) ; foreach my $key ( keys %{$data->{'node'}} ) { foreach my $loopback ( @{$data->{'node'}{$key}{'loopback'}} ) { print "key = $key; loopback = $loopback\n" ; } }

Output:

key = edge2; loopback = 10.6.21.10 key = edge2; loopback = 10.12.71.14 key = edge1; loopback = 172.16.254.10
