Mapping to simplify structure of XML for File Adapter

Question

Hi everybody
Here is a short question regarding the restructuring of an incoming IDoc message to an outgoing file.
The IDoc has the structure:
-IDoc
___-->Segment A1           
______--> Segment B1   
_________-->Segment C1 
_________-->Segment C2 
_________-->Segment C3 
______--> Segment B2   
_________-->Segment C4 
_________-->Segment C5 
_________-->Segment C6 
___-->Segment D1       
You can see that Segment A1 occurres only ones, but can have several child nodes B. Also Segment B can have several Child nodes.
To transfer this Idoc to a flat file we have to create a flat structure as I understood form several Threads. So the target should look like this:
-->root 
_____-->Segment A1           
_____-->Segment B1   
_____-->Segment C1 
_____-->Segment C2 
_____-->Segment C3 
_____-->Segment B2   
_____-->Segment C4 
_____-->Segment C5 
_____-->Segment C6 
_____-->Segment D1
If I map the structure just one by one, I loose the last segments of C and it look like:
-->root 
_____-->Segment A1           
_____-->Segment B1   
_____-->Segment C1 
_____-->Segment C2 
_____-->Segment C3 
_____-->Segment B2   
_____-->Segment D1
How can I manage to get the needed target structure. I thought of using function <i>sortbykey</i> or <i>sort</i>, because I have values in C and B which are equal.
Any help?

Hi Again on this topic
yes stefan, obviously we have to have a flat structure. Based on our frustration we tried to send our structure from an Idoc directly to the file adapter and the following intresting thing came out:
The Idoc structure looked like this
-->root
_____-->EDIC_040
_____-->Segment A1
________-->Segment B1
___________-->Segment C1
___________-->Segment C2
___________-->Segment C3
________-->Segment B2
___________-->Segment C4
___________-->Segment C5
___________-->Segment C6
_____-->Segment D1
After sending this structure to the file adapter and ignoring that the stucture is not flat one we got this in our file:
Segment A1Segment B1
Segment C1
Segment C2
Segment C3
Segment B2
Segment C4
Segment C5
Segment C6
Segment D1
We got nearly what we wanted, just that a new line is missed between  Segment A1 and Segment B1. We tried to use 'nl' but it does not work. Any Ideas on how to get Segment B1 into the next row??
