Tree from directory listing

Hi list!

Does someone know a method to create a nested xml Tree structure from file
listing with paths?

eg.
...
<file name ="f1.xyz" path="/test/"/>
<file name ="f2.xyz" path="/test/folderInFolder/"/>
<file name ="f3.xyz" path="/test/folderInFolder/"/>
<file name ="f4.xyz" path="/test/folderInFolder2/"/>
<file name ="f5.xyz" path="/test2/folderInFolder3/"/>
...

to

<folder name="test">
    <folder name="folderInFolder">
        <file name="f2.xyz"/>
        <file name="f3.xyz"/>
    </folder
    <folder name="folderInFolder2">
        <file name="f4.xyz"/>
    </folder
<folder name ="test">
    <folder name="folderInFolder3">
        <file name="f5.xyz">
    </folder>
</folder>

Maybe anyone solved a similar problem?
