Hi, I'm having exactly the same issue and was wondering how did you manage to solve your problem.
We have recently upgraded from Informatica 9.5 to 9.6 and somehow the same conditions which were working in 9.5 are not working in 9.6.
My session has all 6 properties set as:
"Null content representation" - No Tag
"Empty string content representation" - No Tag
"Null attribute representation" - No Attribute
"Empty string attribute representation" - No Attribute
Custom Properties -> WriteNullXMLFile=NO
Custom Properties -> SuppressNilContentMethod=ByTree
Were you able to resolve your issue? Please shed some light.
Thank you !
Am also facing same problem.Any resolution for above question.
