    // describe current node:
    Element current = (Element) walker.getCurrentNode();
    //System.out.println(indent + "- " + ((Element) current).getTagName());

    // store elements which need to be moved
    if (topParent != null) {

    }

    // traverse children:

    }

    // return position to the current (level up):
