Hello,

I have a flow that transforms an XML message into a COBOL copybook format. The resultant commarea is then sent to our CICS system and a modified commarea comes back ready to be transformed into another XML message using a different flow.

The originating XML message has many elements and in the first compute node, only a subset of the elements are needed to populate a particular copybook.

In the response compute node, where the modified commarea (MRM format) is transformed back to XML, once again, only a subset of elements need to be mapped from the commarea.

The problem is that the resultant XML is only a subset of the original XML structure because I've only mapped the necessary MRM fields to XML elements, but I want a complete XML message (ie the same structure) with the fields that were not mapped (blanked would be OK).

Is there a way of constructing a complete XML message that is the same structure as the original message (that valid against the imported DTD), but without having to have hundreds of esql statements to construct the entire message.

Here's an example:

incoming XML:
<Test>
<Input1>1</Input1>
<Input2>2</Input2>
<Output1></Output1>
<Output2><Output2>
</Test>

Input1 and Input2 are tags containing input data and Output1 and Output2 are tags for output

In the return xml, I don't care about having data in the Input1 and Input2 tags, but I still need them there. If I just map Output1 and Output2 the xml out of the compute node looks like

<Test>
<Output1>result1</Output1>
<Output1>result2</Output2>
</Test>

Is there a way of getting the whole structure back, even with blanked tags?

Thanks
Alan
