Hello,
I have created an XSD using DFDL domain. Its working fine.
But For a Scenario like if 3 elemens are present in XSD and tab is missing for 2nd element then 3rd value is getting assigned to 2nd element and also its not failing.
EX:- Name,Id,Data are present in XSD and input is Rani(Tab)MQ; In the input Id value is missing and i want throw as invali data.But MQ got assigned to Id and its not failing.
Can you please help me to resolve this.  |

Post your DFDL schema and the results of a DFDL trace with the invalid data.
Then we'll be able to help you.

Also, and for the record, it's behaving as designed. If you have 3 fields with tab delimiters and only provide 2 items, of course it's going to assign the 3rd to the 2nd - how does it know that's supposed to be the 3rd?
The question is why it's not complaining that there are not 3 elements. Your schema will illuminate this.

Vitor is correct. You need to set separatorSuppressionPolicy to 'never' on the parent group. That will force the DFDL parser to complain if any fields are missing.

| If you would like DFDL to fail specifically because the content of element 'Id' is incorrect, then you can use a DFDL assert or discriminator on 'Id' that checks its value. So if it is missing and the content of 'Data' gets read into that 'Id', you will get an error. That all assumes that 'Id' and 'Data' can be distinguished. |
