Directory structure of rubytree

Hi, I am working on a project in which if we click on to the browse
button then it should show only the directories,which is possible using
the rubytree that is a gem.I have require that gem too but i am not
getting the graphical representation of the directories structure where
in we can save or retrive the documents.If anybody Knows about this plz
reply me as soon as possible. It willbe well and good if i get a
practical examlpe or code for this. Thank you in advance.Hope to get the
reply fast.thanxs.

Below code can be used to convert directory structure in xml.

require 'rubygems'
require 'rexml/document'

class DirectoryStructure
@@excludes = ["..","."]
@@doc = REXML::Document.new %{ <?xml version="1.0" encoding="UTF-8" ?> }

def self.traverse_directory(root_path)

  #traverse initial directory structure
  folder = @@doc.add_element( 'myroot',{'id' => root_path} )

  #call loop_path with root_path and parent_node
  loop_path(root_path,folder)
  #create xml file
   open( "final_directory_structure.xml", "w" ) do |f|
    f.puts @@doc
  end

end

def self.loop_path(path,parent_node)

dir_entries= Dir.entries(path)

# don't need '.','..'
dir_entries = dir_entries-['.','..']

dir_entries.each do | entry |

# check if directory or file
if File.directory?(path+"/"+entry)

   #Folders Loop -------------------------------------------------
   #Gets the directories of the current node.
   #It changes for each recursive call
   folder = parent_node.add_element( 'folder' ,{'label' =>entry
,'file_path' => path+"/"+entry } )
   loop_path( path+"/"+entry, folder )
else
   #Files Loop ------------------------------------------------------
   file = parent_node.add_element( 'file' ,{'label' =>entry ,'file_path'
=> path+"/"+entry } )

end

end

end

#first call to traverse directory
self.traverse_directory("Authentication/Authentication")

end
