I'd use xml-simple.

% gem install xml-simple

Then a program like this:

	require 'xmlsimple'
	require 'pp'
	pp XmlSimple.xml_in('xml.xml')

will produce this structure of hashes and arrays:

{"name"=>"c",
  "folder"=>
   [{"name"=>"folder1",
     "subfolder"=>
      [{"name"=>"sub1", "content"=>"\n   "},
       {"name"=>"sub2", "file"=>[{"name"=>"file1"}, {"name"=>"file2"}]},
       {"name"=>"sub3", "file"=>[{"name"=>"file1"}]}]},
    {"name"=>"folder2",
     "file"=>
      [{"name"=>"file1", "content"=>"\n     "},
       {"name"=>"file2", "content"=>"\n     "}]}]}

You can customize the printing to suit your taste. There are different  
options to xml-simple that let you control the array/hash structure  
that gets generated.
