G'day calebcall,

Using Data::Dump to show the structure of $result:

#!/usr/bin/env perl

use strict;
use warnings;

use XML::Simple;

my $xml = XML::Simple->new();

my $result = $xml->XMLin(<<'EOX');
<?xml version="1.0" encoding="utf-8"?>

I get:

{
  CommandResponse => {
    DomainGetListResult => {
      Domain => [
        { Expires => "03/31/2015", ID => 8888888, Name => "Domain1.com

        { Expires => "02/25/2015", ID => 8888889, Name => "Domain2.com

        { Expires => "04/01/2015", ID => 8888899, Name => "Domain3.com

        { Expires => "05/20/2015", ID => 8888999, Name => "Domain4.com

      ],
    },
    Paging => { CurrentPage => 1, PageSize => 50, TotalItems => 4 },

So, changing your loop to this:

foreach my $domain (@{$result->{CommandResponse}{DomainGetListResult}{
+Domain}}) {
    print $domain->{Name} . "\n";
}

I get:

Domain1.com
