Complex Sync receiver JDBC scenario

Question

Hi everyone,
Scenario - Web Service (async) -> PI -> JDBC (sync)
Request structure (not typing the standard format, but I am following that)-
<MT_req>
<Statement1>                     SELECT # 1
<access>
<filenumber/>
<segment1>
<field2>
</segment1>
<segment2>
<field2>
</segment2>
</Statement1>
<Statement2>                     SELECT # 2
<access>
<filenumber/>
<segment1>
<field2>
</segment1>
<segment2>
<field2>
</segment2>
</Statement2>
</MT_req>
Select # 1 will return FILENUMBER and SEGMENT1 (In this case, segment2 will be blank?). Select # 2 will return FILENUMBER and SEGMENT2 (In this case segment1 will be blank).
There can be multiple occurrences of segment 1 & 2. Not always segment 1 & 2 will share same FILENUMBER.
The target payload should look like -
<MT_resp>
<row>
<FILENUMBER>                 (if seg1 & 2 share the same FILENUMBER)
<segment1> fields with values </segment1>
<segment2> fields with values </segment2>
</row>
<row>
<FILENUMBER>                 (if seg1 & 2 don't share the same FILENUMBER)
<segment1> fields with values </segment1>
<segment2> fields with NO values </segment2>
</row>
</MT_resp>
Briefly it means that if FILENUMBER is same, then "merge" the 2 segments in the same message row.
Can this be handled in the message mapping? If yes, how? If no, then what can be done?
I hope I am able to explain it properly. Any help will be highly appreciated.
Thanks for your time and efforts.

Scenario - Web Service (async) -> PI -> JDBC (sync)
So does it mean that you do not want to send the response back to WS? In this case you have to implement a BPM to either discard the response from JDBC or to route the response to some other receiver.
<row>
<FILENUMBER> (if seg1 & 2 share the same FILENUMBER)
<segment1> fields with values </segment1>
<segment2> fields with values </segment2>
</row>
In the source will segment1 and segment2 are present as two different nodes (i.e. in the datatype itself)?
If yes, then below logic should work for creating FileNumber in above case:
Segment1 -->
          --> equalS --> if (Then --> Blank_Constant) --> row
Segment2 -->
to generate the other row node when segment1 and segment2 are not the same just put a Not function after equalS .... second row node needs to be duplicated (duplicate Subtree)
