Transforming non structured XML into structured XML wi

Hello,

I'm trying to write a XSLT style sheet that transforms a non-structured xml
document to a structured xml document and am in troubles :

My xml documents looks like a flat modelization of a treeview :

<row lib="data1" folder1="A" folder2="C" />
<row lib="data2" folder1="A" folder2="C" />
<row lib="data3" folder1="A" folder2="C" />
<row lib="data1" folder1="A" folder2="D" />
<row lib="data2" folder1="A" folder2="D" />
<row lib="data3" folder1="A" folder2="D" />
<row lib="data1" folder1="B" folder2="E" />
<row lib="data2" folder1="B" folder2="E" />
<row lib="data3" folder1="B" folder2="E" />
<row lib="data1" folder1="B" folder2="F" />
<row lib="data2" folder1="B" folder2="F" />
<row lib="data3" folder1="B" folder2="F" />
<row lib="data1" folder1="B" folder2="G" />
<row lib="data2" folder1="B" folder2="G" />
<row lib="data3" folder1="B" folder2="G" />
<row lib="data1" folder1="B" folder2="H" />
<row lib="data2" folder1="B" folder2="H" />
<row lib="data3" folder1="B" folder2="H" />

Basically the first line means that the folder A contains the folder C  which contains data1
And so on for the others
I would need to transform it in the following structured XML document :

<A>
     <C>
     <data1/>
     <data2/>
     <data3/>
     </C>
     <D>
     <data1/>
     <data2/>
     <data3/>
     </D>
</A>
<B>
     <E>
     <data1/>
     <data2/>
     <data3/>
     </E>
     <F>
     <data1/>
     <data2/>
     <data3/>
     </F>
     [...]
</B>

The XML file is dynamically generated so folder names and folder depth are not know in advance.
I can't see how to do that, and I don't event know if it is possible.

Any help, of any sort, would be much appreciated

Regards
