  var jsonBuilder = new xml2js.Builder();  //测试用例
  var xml = "<root>Hello xml2js!</root>";  var obj = {name: "Super", Surname: "Man", age: 23};  console.log(&#39;----------&#39;);  
  // xml -> json
  xmlParser.parseString(xml, function (err, result) {    //将返回的结果再次格式化
     console.log(JSON.stringify(result));
  });  console.log(&#39;----------&#39;);  //json --> xml
