I would have made becomeParentOfAll take an optional "ifEmpty" parameter
(probably a named parameter, but I'm not sure of that).

Done.

   protected <T extends XmlNode> List<T> becomeParentOf(List<T> children, List<T> ifEmpty) {
     if (children != null && children.isEmpty()) {
       return ifEmpty;
