Subject: Combining XML elements based on sub-element value

Hi,

I am trying to modify an XML which has resulted from a turning a DB query to XML. eg.

<?xml version="1.0" encoding="utf-8" ?>
<NewDataSet>
- <Table>
<CommonName>Chimpanzee</CommonName>
<NumberOfAnimals>15</NumberOfAnimals>
<PostCode>BN13LW</PostCode>
<Zoo_ID>4</Zoo_ID>
<ZooName>Brighton Zoo</ZooName>
</Table>
- <Table>
<CommonName>African Lion</CommonName>
<NumberOfAnimals>1</NumberOfAnimals>
<PostCode>BN13LW</PostCode>
<Zoo_ID>4</Zoo_ID>
<ZooName>Brighton Zoo</ZooName>
</Table>
- <Table>
- <Table>
<CommonName>Bengal Tiger</CommonName>
<NumberOfAnimals>3</NumberOfAnimals>
<PostCode>PO49PX</PostCode>
<Zoo_ID>5</Zoo_ID>
<ZooName>Portsmouth Zoo</ZooName>
</Table>
</NewDataSet>

Now I need to combine all the "Table" elements where their subelement Zoo_ID has the same value to produce something like:
<Table>
<tr>
<td>Name</td><td> Chimpanzee</td>
</tr>
<tr>
<td>Name</td><td> African Lion</td>
</tr>
<tr>
<td>Zoo Name</td><td>Brighton Zoo</td>
</tr>
<tr>
<td>Zoo Post Code</td><td>BN13LW</td>
</tr>
</Table>
<Table>
<tr>
<td>Name</td><td>Bengal Tiger</td>
</tr>
<tr>
<td>Zoo Name</td><td>Brighton Zoo</td>
</tr>
<tr>
<td>Zoo Post Code</td><td>BN13LW</td>
</tr>
</Table>

but I am unsuccesful creating a template to do so. Can you give me some pointers?

You need to perform a grouping operation: see http://www.jenitennison.com/xslt/grouping/index.html for some tutorials.

Hi Alberto,

Thank you for your reply and the link. The issue that puzzles me is how to get the value of "all" the Zoo_IDs in my XML and then group by each of those. As the values come from a Database and this transformation is done programmaticaly I am unsure how to create multiple groupings each by the ZOO_ID.

Apologies for my ignorance but quite new to XSLT and it is difficult to get my head around it at the moment
