Hi,
With just the first node commented thus not providing support for
handling the transport tag, the following stylesheet produces the output
you want.
Iam sure this can be extended to handle the transpot tags.
Cheers,

Hello list,
I wish to transform an xml which has level information in each item
(Table) to xml which has hierarchy as stated in those item's element.
<DataSet xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<Table>
<Level>1</Level>
<Description>Cars</Description>
</Table>
<Table>
<Level>2</Level>
<Description>BMW</Description>
</Table>
<Table>
<Level>3</Level>
<Description>316</Description>
</Table>
<Table>
<Level>3</Level>
<Description>Z4</Description>
</Table>
<Table>
<Level>2</Level>
<Description>Citroen</Description>
</Table>
<Table>
<Level>3</Level>
<Description>C2</Description>
</Table>
<Table>
<Level>3</Level>
<Description>C4 coupe</Description>
</Table>
<Table>
<Level>2</Level>
<Description>Alfa Romeo</Description>
</Table>
<Table>
<Level>3</Level>
<Description>156</Description>
</Table>
<Table>
<Level>1</Level>
<Description>Motorcycles</Description>
</Table>
...
...
</DataSet>
Target xml should look something like this:
<NewDataSet>
<Transport name="Cars">
<Brand name="BMW">
<Model>316</Model>
<Model>Z4</Model>
</Brand>
<Brand name="Citroen">
<Model>C2</Model>
<Model>C4 coupe</Model>
</Brand>
<Brand name="Alfa Romeo">
<Model>156</Model>
</Brand>
</Transport>
<Transport name="Motorcycle">
...
</Transport>
</NewDataSet>
So, based on the Level element in the source xml for each Table entry,
an appropriate subtree must be constructed and inserted in target xml.
Levels are ordered following this pattern:
1,2,3,3,...,3,2,3,...,3,...,1,2,3,3,...,2,3,...,3
Busting my head over this for two days now, help appreciated. If only I
could find the guy who created this "flat" xml...$%##@@!
