I have the following problem. My company "lost" the .xsd file they used to export products from an Excel file to an XML file, and now I tried to re-write it myself but I came to a problem of how to split a field that has values separated by commas.

Here is an example from the Excel file. http://i.stack.imgur.com/KICvP.jpg

It's the second to last field named masterreference. Now the problem is writing an .xsd file that will through the Excel XML export come up with the following structure:

<universalld>0AF1AA0F18FB44F5C125701800445CC3</universalld>
<brand>ACEC</brand>
<type>Canister</type>
<commercialname></commercialname>
<model>AT 81, 82</model>
<importance>0</importance>
<diameter>32 mm</diameter>
<masterreferences>
<masterreference>FL 11</masterreference>
<masterreference>T 40</masterreference>
</masterreferences>
<productpictureno></productpictureno>
</cleaner>

This is the .xsd I have right now. http://i.stack.imgur.com/YbIew.png

Can someone help me? Thanks!
