Need to cover few scenarios in pipeline

1. As i am not sure about your data set, might creating confusion. Try this option- For join - first inter change input0 (38) to input 1(csv parse ) and use left outer / outer join ,also uncheck unmatch error view option. Then can use router to determine you found the correct lookup data or not. If found then save in file else send mail.
2. For file name , creat a child pipeline with xml parser and file write (also remove these from parent)Add one pipeline param (filename ) in child pipeline and use that in file write. Call this child pipeline using pipeline execute.

Thanks,
Supratim
