Sort incoming XML message

Question

Hi
Is there a standard way in PI to sort the incoming XML message within the message mapping before doing the mapping itself?
The scenario would be an incoming Flat file with header and item data records, and we will be mapping it in PI to create IDOC messages based on the same Header segment. So for the same Header Data I would like to create a single IDOC. But the incoming file would be unsorted, so I would need to sort it first based on the header segment some way.
Ideally, we would like to do all of the mapping in the graphical mapping tool and not use a UDF.
Thanks

Answer 1

I already tried Sort, but it doesnt work the way I want.
Say I have inbound XML as
<hdr1>
<hdr2>
<itm1>
<itm2>
<itm3>
it needs to be mapped to an IDOC as
<hdrsegment>
<itmsegment>
I mapped XML header data to IDOC after sorting, and that works fine. The issue comes on assigning the inbound XML Item data to IDOC Item segment. It is creating the correct Number of segments, but when assiging the fields to IDOC fields, it is using unsorted data ie the data as received, not the sorted one which I did for IDOC Node, and for Header fields.
What I really want is to sort the data once, and then use that in the mapping.
