Greetings, Requirement goes like this. I have perl script reading from a MQ Series queue. This queue has messages in form of XML.For example- 1 message is like -

<CLIENT_INFO> <LOCATION> New York </LOCATION> <FIELD> FINANCE GROUP </FIELD> <NO_OF_WORKERS> 123 </NO_OF_WORKERS> </CLIENT_INFO>

My perl script reads messgaes from this queue, and drops them to another queue after creating a backup in a text file. My requirement is I have check the value of a particular tag for example, value of <FIELD>, if that is say "FINANCE GROUP", I have to change it to "FINANCIAL SYSTEMS" and then drop to the other queue. I tried below, but for some reason it did not work. COuld you please help. Pl note I would prefer doing below way or other wise I have XML Parser installed. Sample of my script - 

# Connect to qmgr
$qmgr = MQSeries::QueueManager->new ( QueueManager => $hOpts{m}, AutoC
+onnect => 0)
        or die "Unable to instantiate MQSeries::QueueManager object\n"
+;

$qmgr->Connect() or die("Unable to connect to queue manager\n" .  "Com
+pCode => " . $qmgr->CompCode() . "\n" .  "Reason => " .
 $qmgr->Reason() .  " (", MQReasonToText($qmgr->Reason()) . ")\n");

# open input and output queues
my $qIn =MQSeries::Queue->new(QueueManager => $qmgr, Queue => $hOpts{i
+}, Options=>MQSeries::MQOO_INPUT_SHARED )
         or die "Unable to open queue $hOpts{i}" ;

my $qOut=MQSeries::Queue->new ( QueueManager => $qmgr, Queue => $hOpts
+{o}, Options=>MQSeries::MQOO_OUTPUT | MQSeries::MQPMO_S
ET_ALL_CONTEXT )
         or die "Unable to open queue $hOpts{o}" ;

until( $time_to_die )
{
        my $message = MQSeries::Message->new(MsgDesc=>{Persistence=>1}
+);

    # Get message from queue
        $result = $qIn->Get( Message => $message, Sync=>1, Wait=>-1 );
+      
my $msgDescRef = $message->MsgDesc;
my $data = $message->Data;
my $field_name = GetXMLValue($data, "FIELD");
if ($field_name eq 'FINANCE GROUP')
{

$field_name = 'FINANCIAL SYSTEMS';

$msgDescRef->{"FIELD"} = $field_name ;
}
        for(1..$num_retries) {
                $result = $qOut->Put( Message => $message, Sync => 1,
                                PutMsgOpts =>{ Options=>MQSeries::MQPM
+O_SET_ALL_CONTEXT ||
                                                                      
+          MQSeries::MQPMO_FAIL_IF_QUIESCING});
                if ($result > 0) { last; }
               
                sleep $time_to_wait;
        }
