code: private static Elements getElementsByTag(Element e, String tag) {
          Elements es = e.getElementsByTag(tag);
          es.remove(e);
          return es;
      }
docs: Jsoup's Element.getElementsByTag(Element e) includes e itself, which is
  different from W3C standards. This utility function is exclusive of the
  Element e.
