1.Java代码

 Document doc = DocumentHelper.parseText(xml);

   // Element rootE = doc.getRootElement();

 List modules = doc
                                    .selectNodes("//auth/auth-user/sys-modules/sys-module");
                            if (null != modules) {
                                for (int i = 0; i < modules.size(); i++) {

                                    Element e = (Element) modules.get(i);
                                    System.out.println(i
                                            + e.elementText("moduleid"));

                                }// end of for
                            }// end of if
