( #3333=superdoc: print w/replies, xml ) Need Help??

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' => [ '', '' ] }, 'edge1' => { 'community' => [ 'something' ], 'loopback' => [ '' ] } } };

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></loopback> </node> <node name="edge2"> <community>anotherthing</community> <loopback></loopback> <loopback></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" ; } }


key = edge2; loopback = key = edge2; loopback = key = edge1; loopback =
