Sub node is not getting created

Question

Hi Experts
I have IDOC to SOAP scenario, here the subnode is not getting created in the main node. please help me
Structure is given below
Source
Matmas
      IDOC
          e1m -
(1...9999 ) occurance
Target
Target
XMLDATA  --- (1.. UNBOUNDED)
     SUBNODE1 ---(1.1)
          SUBNODE2 ---(1.)  -- UNDER SUBNODE1
          SUBNODE3----(0...UNBOUNDED) -- UNDER SUBNODE1.
Quesion 1.
now i want XMLDATA node to be repeated as many times as e1m comes from source along with both the subnodes 2 and 3 at target side.
but i could see only subnode2 is getting created not the subnode3 while testing.
May i know why is this happening.
I want the SUBNODE3 also be created.
Note the occurance of SUBNODE3  is 0.. unbounded
Question 2:
I want the SUBNODE3 also to be repeated as many times as e1m node comes from source.
For example:
e1m comes twice then the target should be as below
XMLDATA  --- (1.. UNBOUNDED)    
SUBNODE1 ---(1.1)
          SUBNODE2 ---(1.)  -- UNDER SUBNODE1
          SUBNODE3----(0...UNBOUNDED) -- UNDER SUBNODE1.
SUBNODE3----(0...UNBOUNDED) -- UNDER SUBNODE1.
XMLDATA  --- (1.. UNBOUNDED)    
SUBNODE1 ---(1.1)
          SUBNODE2 ---(1.)  -- UNDER SUBNODE1
          SUBNODE3----(0...UNBOUNDED) -- UNDER SUBNODE1.
SUBNODE3----(0...UNBOUNDED) -- UNDER SUBNODE1.

Please see the below logic:
E1MARAM --> XMLNODE
E1MARAM --> useOneAsMany_customUDF -->SUBNODE3
E1MARAM/MATNR -->  useOneAsMany_customUDF --> SUBNODE3/MATNR
E1MARAM/xyzfield -->  useOneAsMany_customUDF --> SUBNODE3/xyzfield

         <SUBNODE3>
            <MATNR>1234</MATNR>
         </SUBNODE3>
      </SUBNODE1>
   </XMLDATA>
</ns0:MT_Test>
useOneAsMany_customUDF
for(int i =0;i<var1.length;i++)
   for(int j=0;j<var1.length;j++)
      result.addValue(var1[j]);
    result.addContextChange();
Hope it helps!
