1. Traverse the CmdTree node from the root CALL process_node(CmdTree.root)
2. START process_node:
      If the CmdNode is not a leaf node then
            2.1.  Process all the child nodes of the current node first. CALL process_node(node)
            2.2.  After processing all child CmdNode. Set current node visibility
                     If all the childs are removed then
                        node.visible = False

3. START action_node:
      if the node is not visible then
          Remove the node from the XML
