I have following input:
<Transaction>
<TotalAmount>67.89</TotalAmount>
<TotalVATAmount/>
</Transaction>
And I want following output:
<BusinessObject>
<Amount>67.89</Amount>
<VATAmount></VATAmount>
</BusinessObject>
I tried following:
I created two msg sets (Transaction and BusinessObject) with XML1 formats.
In my msg flow, MQInput Node sets parser to MRM and format to XML1 (so that I can validate the input msg).
Then use RCD to change the parser from MRM to XML.
Then is the mapping node to map Transaction to BusinessObject.
The output that I got is:
<BusinessObject>
<Amount>67.89</Amount>
<VATAmount>0</VATAmount>
</BusinessObject>
In my Transaction Msg Set, both TotalAmount and TotalVATAmount are local elements of type decimal.
Why does this extra '0' appears in my output <VATAmount>??

Is it a default value in your model?

No. I haven't given any default value in my msg def.
Actually, when the msg enters the flow, the parser itself assigns the value of '0' to this element.

Ah. So it's a Null Element rendering option.
You could play with that in your model, or you could add something to set the value of the element to null.

Have you encountered this problem earlier? Like, the parser assigns an unwanted value to an empty tag?
I had my flow in debug perspective and checked it. The tree looked like this:
Message
Properties
MQMD
MRM
TotalAmount = 67.89
TotalVATAmount = 0
From where does this zero come? I need to use MRM parser because I want to validate my input msg against the msg set.
Further I used mapping node to map input to output. Now I am planning to use compute node and build my output msg tree through ESQL code.
If you want I can email you my mxsd and you can check it.

From your link I found following:
| Quote: |
The properties Encoding Null Num Val and Encoding Null Non-Num Val provide a value (if needed) to represent a null value. For an element of type string, this might be null or unspecified while for a number it might be 0 or 0.0.
|
In my msg set messageset.mset, I have created a physical format XML1.
In this I have following:
XML representation of null value
Encoding Numeric Null - NullEmpty
Encoding Numeric Null Value - disabled
Encoding Non-Numeric Null - NullEmpty
Encoding Non-Numeric Null Value - disabled
Now, where possibly do I have the value of 0 setup?
