Hello guys,
I'm back after a long hibernation. And was immediately hit with this in my new assignment.
Situation:
A message flow that gets an XML on the MQInput node where the parser is set to XMLNSC. Then follows a compute node where the message is transformed to a COBOL copybook structure via a bunch field assignments from source to target.
But, when an XML control character is put into one of the fields in the XML (or example < instead of <), the output message still has < instead of the character <. I had expected the XMLNSC parser to convert it back to the actual character when it builds the message tree.
Am I missing some other step that needs to be done here to get that conversion to happen?
Please advise.

The correct term for < is 'XML entity'.
The XMLNSC parser *does* decode entities. If the content of a tag or attribute contains < then the XMLNSC parser will put < into the value of the syntax element in the message tree.
Please post
- the input message, or a relevant fragment of it
- Trace node output
- output message, or a relevant fragment of it |

Kimbert -
I apologize for pulling the trigger too soon. I should have first suspected the message producing application. However, the tool we use for MQ browsing(AppWatch) did not indicate the inherent problems and neither did RFHUtil. By sheer luck, I just opened my java client to browse the message on the queue and dump the contents into a file on my local system. Horrified by what I saw.
The sending application has put the following into the message when they wrote to the queue.
<DataTag>&quot; This ain&apos;t right &quot;</DataTag>
If you observe how they have escaped it, it appears as though the & character in the escape sequence was escaped again:) 
Gotta love it    
Sorry again!!
