I've used Win32::OLE and Win32::OLE::Enum to grab WMI information. As for enumerating your output, what are you trying to accomplish? I'd tackle this differently based on if you were printing a tree menu of the data, or simply reporting on it.

Either way I've included a basic example of grabbing a CPU value from WMI. This script contains more source the necessary, to assist with learning.

#!perl


#Change These Variables (Leave all variables BLANK if connecting to lo
+cahost)#
$server="";
$remote_user="";
$remote_pass="";


use Win32::OLE qw(in with);
use Win32::OLE::Enum;

Win32::OLE->Option(Warn => 0);

##WMI Connect##
$WMI = Win32::OLE->new('WbemScripting.SWbemLocator');
if(!$WMI){
    print Win32::OLE->LastError();
    exit;
}

$Services = $WMI->ConnectServer($server, "root/cimv2", $remote_user, $
+remote_pass);
if(!$Services){
    $err_tmp_raw=Win32::OLE->LastError();
    $err_tmp=Win32::OLE->LastError();
    $err_tmp=~s/\'/\\'/g;
    $err_tmp=~s/\"/\\"/g;
    
    $err_tmp='Access Denied' if($err_tmp=~m/denied/i);
    $err_tmp='WMI Not Installed' if($err_tmp=~m/class not registered/i
+);
    $err_tmp='RPC Server Unavailable' if($err_tmp=~m/rpc server is una
+vailable/i);
    
    print "$err_tmp\n";
    print Win32::OLE->LastError();
    exit;
}


my $Processor_set = $Services->InstancesOf("Win32_Processor");

foreach my $object (Win32::OLE::Enum->All($Processor_set)){
    print "CPU: $object->{'caption'}\n";
    print "CPU Utilization: $object->{'LoadPercentage'}\n";
}
