I want to know how to make the DFDL parser to include the optional delimiters when serializing the output.

For example if my dfdl model contains 5 fields (optional) but my input only contains 1,3 &4 I want to write out the below when serializing the output.

FIELDS1||FIELD3|FIELD4||

Thanks

Don't make the fields optional. Make them mandatory but nillable.
What your output shows is 5 fields with post delimiter '|' and null value for field 2 and field 5...

Have fun

You need to set separatorSuppressionPolicy to 'trailingEmpty' or 'never'

See
http://www-01.ibm.com/support/knowledgecenter/SSMKHH_9.0.0/com.ibm.dfdl.spec.doc/dfdl_index.htm
Section 14.2 to decide which one is appropriate for your data format.

Awesome, this (separatorSuppressionPolicy to 'trailingEmpty' or 'never') solved my problem!

Thanks guys as always
