I am trying to map an XML document to CWF and the $source references appear to be evaluating to NULL. One of the child elements is named exactly the same as the root element and it's the only thing I can think of that would be causing the problem.

XML document:

Code:

<VC_PICKSLOT_IFD>
<CTRL_SEG>
<TRNNAM>abc</TRNNAM>
<TRNVER>123</TRNVER>
<VC_PICKSLOT_IFD>
<PRTNUM>123456</PRTNUM>
</VC_PICKSLOT_IFD>
</CTRL_SEG>
</VC_PICKSLOT_IFD>

Using mapping node, this statement doesn't work (target element is not created):

Code:

$target/QBP015/Item = $source/VC_PICKSLOT_IFD/CTRL_SEG/VC_PICKSLOT_IFD/PRTNUM

Using compute Node, this statement works great:

Code:

SET OutputRoot.MRM.Item = InputRoot.MRM.CTRL_SEG.VC_PICKSLOT_IFD.PRTNUM;

Any ideas?

Thanks,
Michael

The path which the mapping node has generated contains the root element name. This is not required when the runtime parser is MRM. Check that you have set the 'Runtime Parser' property of your message set to 'MRM'.

Thanks for your reply Kimbert.

The runtime parser is set to MRM and all of our other maps reference root elements in the same way and still work. If we rename (though not an option) the child VC_PICKSLOT_IFD element to something like VCPICKSLOTIFD, the existing map works fine...

Problem has gone away! (though not solved). As it turns out, the vendor's spec was wrong and the child element VC_PICKSLOT_IFD is really supposed to be VC_PICKSLOT. I am still puzzled by this and will post my results when/if I am successful.
