Im having an XML document which I have to validate.



<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<!DOCTYPE XML_BOPOCMQ>

<WfMessage>
<WfMessageHeader>
<ResponseRequired>Yes</ResponseRequired>
<UserContext>This data is sent back in the response</UserContext>

</WfMessageHeader>
<ProcessTemplateCreateAndStartInstance>
<ProcTemplName>Loan</ProcTemplName>
<ProcInstName>Loan</ProcInstName>
<KeepName>true</KeepName>
<ProcInstInputData>
<CustomerDetails>
<Name></Name>
<DateofBirth>12/05/1958</DateofBirth>
<Age>23</Age>
<Gender>Female</Gender>
</CustomerDetails>
</ProcInstInputData>
</ProcessTemplateCreateAndStartInstance>
</WfMessage>

I need to parse this XML through MQ workflow and validate it.

If the Name is a null value, a message should be sent to an error queue.

Can anyone please assist me on how to do this .

If I understand correclty, you want to validate if a datastructure memeber is set before triggering the process.

MQWorkflow does not validate if a datastructure member is set or not before starting the process instance

You can achieve this by posting the message to a custom queue where a custom listener will validate the XML and pass only the successfull messages to EXEXMLINPUT queue. The messages that fail can be posted to an 'error' queue
