I have the following XML file: 
<config>
    <server>
        <name>server1</name>
        <file>
            <filename>/etc/named.conf</filename>
            <filename>/etc/nsswitch.conf</filename>
        </file>
    </server>
    <server>
        <name>server2</name>
        <file>
            <filename>/etc/named.conf</filename>
            <filename>/etc/nsswitch.conf</filename>
            <filename>/etc/hosts</filename>
        </file>
    </server>
</config>

I can read it no problem using XML::Simple. Where I have problems is that the filename portion can have a different number of entries per server element. In other words, just as the example above, server 1 has fewer entries than server 2. If they have the same number of entries I can simple use 
{server}->{file}->{filename}->[0]
{server}->{file}->{filename}->[1]

...which isn't particularly elegant, but works well. I'm having trouble accessing the hash elements as a loop within in the loop. Any ideas? My sample code to do some of this is below: 
use XML::Simple;
use Data::Dumper;

$xml = new XML::Simple (KeyAttr=>[]);
$data = $xml->XMLin("xml.xml");

#print Dumper($data);

foreach $machine (@{$data->{server}})
{
    $name=$machine->{name};
    print "$name\n";
    $file1=$machine->{file}->{filename}->[0];
    $file2=$machine->{file}->{filename}->[1];
    $file3=$machine->{file}->{filename}->[2];
    print "\t$file1 $file2 $file3\t\n";
    

}
