Retrieve access rights for folders in DOORS

I need to create a script that will loop through all of the folders in each project and display the permissions for each group that has permissions. For example the script would print the following:

Project ABC
      Folder 123
             DB Managers   RMCDA
             DB Users          RMC
             ABC Group      RC

     FolderABC
            ProjMgrs          RMCDA
            Developers      RM
            Reviewers       R

Major Project XYZ
     Documents
             DB Mgrs      RMCDA
             Doc Reviewers  RM
             Doc Editors        RMCD

How do I get this information using DXL?
