Generate XML of selected folders and files

programming flash
1

I am trying to generate XML of a user selected folder and inner folders along with the files recursively. Structure of the XML generated should be as the user selected folder.

I am able to list all the folders and files in the selected folder. I am unable to find a way to generate the same structure, I am unable to think of a way to replicate the depth of folder in XML. Any ideas to find solutions??
