I have restriction to use only Mapping node

I am having this requirement:
We have comma separated String coming in and loop it over in output

Input Message:
Code:
<Input>
<String>A,B,C</String>
</Input>



Output Message:
Code:
<Output>
<Loop>
  <Code>A</Code>
</Loop>
<Loop>
  <Code>B</Code>
</Loop>
<Loop>
  <Code>C</Code>
</Loop>
</Output>



Can we somehow achieve this in Mapping node may using XPath?

Tried using fn:tokenize to split the string but not sure how we can loop it over the Output element.

What would be the best options to do this in mapping node if any?

Done with Custom Java

Code:


   public static MbElement mbElMove(MbElement inString) throws MbException {
      String string = inString.getValueAsString();
      String[] array = string.split(",");
      MbElement root = inString.copy();
      MbElement loop = root.createElementAsFirstChild(MbElement.TYPE_NAME,"Loop", null);
      try {
         for (int i = 0; i < array.length; i++) {

            MbElement code = loop.createElementAsLastChild(
                  MbElement.TYPE_NAME, "Code", null);
            code.setValue(array[i]);
         }

      } catch (MbException e) {
         throw (new RuntimeException(e));
      }
      return loop;
   }
