Hi gus!!

I'm using XML::Parser to parse the following XML:
<level name="Exanet admin" value="1">
    <menu cliname="NFS" clicmd="nfs">
        <menu cliname="Exports" clicmd="exports">
            <command clicmd="add" state="nfsExportsAdd"/>
            <command clicmd="edit" state="nfsExportsEdit"/>
            <command clicmd="view" state="nfsExportsView"/>
        </menu>
        <menu cliname="Configure" clicmd="configure">
            <command clicmd="set" state="nfsConfigSet"/>
            <command clicmd="view" state="nfsConfigView"/>
        </menu>
    </menu>
</level>

This XML holds a menus tree and available commands in each menu. I parse the file using the Objects style like that: 
my $parser = new XML::Parser(Style => 'Objects');
my $xml = $parser->parsefile('test.xml');

I want to be able to print this menu to the user (on Unix, not to browser necessarily), therefore I have to iterate recursively on $xml returned from parsefile, something like:
&printXML($xml);

sub printXML {

  my $ref = shift;

  if (ref($ref) eq 'HASH') {
    print "Type: HASH\n";
    while (($key, $val) = each(%{$ref})) {
      print "key: $key, val: $val\n";
      &printXML($val);
    }
  } elsif (ref($ref) eq 'ARRAY') {   # kids
    print "Type: ARRAY\n";
    for (@{$ref}) {
      print "bla: $_\n";
      &printXML($_);
    }
  } elsif ($xml->isa('HASH')) {   # elements
    print "Type: hash object\n";
    while (($key, $val) = each(%{$ref})) {
      print "key: $key, val: $val\n";
      &printXML($val);
    }
  } else {   # text
    print $ref, "\n";
  }
}

from what I read, there can be only hash refs, array refs and hash objects inside $xml.
the thing is that I get the following error while executing the above: "Can't call method "isa" unblessed reference at on test.pl line 103".

Can anyone shed a little light? and maybe note about the above code
