Hi All,

I have an input message as below

Code:

Sample Response Message:
<?xml version="1.0" encoding="UTF-8"?>
<?ABHeader version="1.0"?>
<?ABEnvelope>
<Application_ID>rrr</Application_ID>
<Password/>
<Message_ID>FtestE</Message_ID>
<Message_Format>XML</Message_Format>
<Transaction_Type>moneytransfer</Transaction_Type>
<Payload><![CDATA[OG4341432 54543 testing tsting testing 203203700.00C1 2.500000000 0.000000000 0.000000000 0.00D 0.000000000 0.000000000 0.000000000 0.000000000N 0.000000000N 0.000000000N]]></Payload>
</ABEnvelope>

In my java compute node, Im trying to extract the payload which is a CDATA . the code im using is as below

Code:

String payload = outMessageBody.getFirstElementByPath("/ABEnvelope/Payload" );

But this always results in a null pointer exception. Is there a different way to extract CDATA section from an XML in a Java Compute node ?

Thanks,
Deepesh

Are you positive that the contents of the CDATASection are actually the value of the element containing the CDATASection?

Have you taken a trace of the message flow structure to confirm that?

You need to check to see what type of object the getFirstElementByPath() call returns to you.

Hint: It is not a String.

Your XML also looks invalid but they may just be an artifact of your copying it to here.

In case you didn't get mqjeff's suggestion...put in a Trace node, and look carefully at the output.
