Question for support of community for an UDF

Question

Hello,
because we are not really able to write Java-Code we have a question for support to the community!
We have a mapping were we get some strings. These strings containing data which we have to map to certain fields in target structure.
Example:
001GIE;002090429;0030853;005D  ;007TCT ;010TTNU9457423 ;01140;01296;013SCI01;019
4N ;02145G1;027E;0300;033V;03508388;03604508;03703880;039003054 ;040003054
The requirement is that we have to identify the fields to map by it's number, like "001GIE" means 001 field in target structure.
So how to do an UDF? We need to parse the string and put the found strings into right position in an array e.g. But how to get this result to the single target-fields in target structure?!
And another problem in example: how to get data if the identifier (019) and the data (4N) is divided by an end of line (see example)?!
Do you have some ideas?! We highly appreciate your help!

Hi Fritz,
Let us address the problem one by one.
1. You might need to change the source structure to :
-root 1..1
--Value 1..unbounded
Please note root and Value are the names given by me you can use any names as per your wish. But we cannot have the source as you specified, will this source be ok for you?
2. Give File content conversion parameter
recordset name = Vale
Value.endSeparator 'nl'
By doing this there will be a Value node created when the source file has a newline character
3. In message mapping create two UDF
*UDF1 (Simple ?UDF with input field named *input )
for (int i=0;i<input.length;i++)
   output += input<i>;
return output
*UDF2 (Simple UDF with input field named input)*
int i = 1;
String [] value = new String[112];
while (input.indexOf(";") != -1)
String counter = "";
Integer i_int = new Integer (i);
if (i<10)
    counter = "00"+ i_int.toString();
else if (i>9 && i<100)
     counter = "0"+ i_int.toString();
else counter = i_int.toString();
if (input.startsWith(counter)) {
  value<i> = input.substring(3, input.indexOf(";"));
  if (input.indexOf(";") != -1 )
     input = input.substring(input.indexOf(";")+1);   
else
  value <i> = "";
i++;
int j;
GlobalContainer globalContainer = container.getGlobalContainer();
globalContainer.setParameter("Output", value);
Now do a mapping like this
Value (context root)--> UDF1 > UDF2> target root node (ie Bewsatz)
By this step you set all the values in global container named Output
3. Now for each target  field call this UDF
*UDF3 (Simple UDF with input field named pos)*
GlobalContainer globalContainer = container.getGlobalContainer();
String[] Value = (String[] )globalContainer.getParameter("Output");;
String outvalue;
if (Value != null) {
outvalue = Value(pos) ;
return outvalue;
Call this UDF for each output field with positions like 1, 2, 3, ...111
Please try this
