Mapping string to n substring and then to m subsubstrings

Question

Hi,
I need some advice/input for a mapping.
MT_Source            Occurence
   ROW                  1
      Customer         1
      Article              1
MT_Target
   ROW                   1:n
      Customer          1
      field1                 1
      field2                 1
      field3                      1
Article field from source is a string of N-times 5 characters
Requirements for mapping are:
The target structure must have N rows
Then the string must be substringed to N-strings
Each field1,2,3 is substring of one substring.
Example
MT_Source looks like:
<row>
customer is X
article is string "12345ABCDE"
</row>
MT_Target must be like:
<row>
customer X
field1       12
field2       34
field3       5
</row>
<row>
customer X
field1       AB
field2       CD
field3       E
</row>
Can it be done with graphical mapping and udf?
Or is it better to do it all in one XSLT or JAVA or ABAP mapping?
Any coding examples u can give are much appreciated.

Hi Anand, Sarvesh,
First of all: thx a lot for all your valuable inputs.
The only issue left for me was the customer. Just Copyvalue never worked because in source structure there is one and only one value, and it never became two.
I've solved this also inside my UDF now. I've added one input (var2) and one output (result5) it and looks like this now:
public void allinONE(String[] var1, String[] var2, ResultList result1, ResultList result2, ResultList result3, ResultList result4, ResultList result5, Container container) throws StreamTransformationException{
int test=var1[0].length();
test=test/5;
for(int i=0;i<test;i++){
     result1.addValue("");
    result5.addValue(var2[0]);
    result5.addContextChange();
String str="";
for(int j=0;j<test;j++)
str=var1[0].substring(j*5,(j*5)+5);
result2.addValue(str.substring(0,2));
result3.addValue(str.substring(2,4));
result4.addValue(str.substring(4,5));
result2.addContextChange();
result3.addContextChange();
result4.addContextChange();
This gets me exactly the output i need.
Again thx for the input
I'll keep exploring
