Answer 1

start by declaring

$groups[stripslashes($file->Platform)][stripslashes($file->Name)]
  [stripslashes($file->Title)] = (object)array(
    'Name' => $file->Name,
    'Title' => $file->Title,
    'Files' = (object)array()
  );

This will get you closer.

You should also check the type of each XMLElement as you get it to see if its an array or a simple object. Then treat accordingly.
