EXCEL XML into XML - using MessageMapping

Question

Hi
I have an XSLT that I use to convert an Excel XML into another XML format.
But I wonder if there a way to do this via the XI Message Mapping instead?. I have tried but I am stuck at the moment trying to identify particular rows. For instance I need to fill the <desc> tag from the 3rd Cell.
[code]
Original Excel data
       Cell1 Cell2   Cell3            Cell4   Cell5
Row1 | AY02  403KITA Concentrator Kit $91.00  22-01-2005
Row2 | AY02  401KITC Oxygen Reg/Flow  $65.00  08-09-2006
[/code]
Input Source file (a cut down version...)
[code]
<Workbook>
<Worksheet>
  <Table>
   <Row>
     <Cell>
        <Data>AY02</Data>
     </Cell>
     <Cell>
        <Data>403KITA</Data>
     </Cell>
     <Cell>
        <Data>Concentrator Kit</Data>
     </Cell>
     <Cell>
        <Data>$91.00</Data>
     </Cell>
     <Cell>
        <Data>22-01-2005</Data>
     </Cell>
   </Row>
   <Row>
     <Cell>
         <Data>AY02</Data>
     </Cell>
     <Cell>
         <Data>401KITC</Data>
     </Cell>
     <Cell>
         <Data>Oxygen Reg/Flow Portable</Data>
     </Cell>
     <Cell>
         <Data>$65.00</Data>
     </Cell>
     <Cell>
         <Data>08-09-2006</Data>
     </Cell>
   </Row>
   </Table>
</Worksheet>
</Workbook>
[/code]
Target XML
[code]
<Batch>
  <items>
    <item>
      <catlgItemNum>403KITA</catlgItemNum>
      <desc>Concentrator Kit</desc>
      <unitPrice>$91.00</unitPrice>
    </item>
    <item>
      <catlgItemNum>401KITC</catlgItemNum>
      <desc>Oxygen Reg/Flow Portable</desc>
      <unitPrice>$65.00</unitPrice>
  </item>
</items>
</Batch>

Hi Peter,
Please create the following user-defined function (cache: context):
public static void getIndexedValue(
     String[] a,
     String[] b,
     ResultList result,
     Container container) {
     //write your code here          
     Integer iB = new Integer(b[0]);
     result.addValue(a[iB.intValue()]);
You can then set up the following mappings:
Row - item
Data (context Row) 
                      getIndexedValue - ...
Constant [1, 2, 3]  /
Best regards
Joachim
