使用 jquery 解析 xml 文件中的 json

Question

这是我的文件，我如何解析它以找到“描述”、“注册日期”等元素？ 谢谢你的帮助。

使用 jQuery 非常简单，它可以像遍历 html 一样遍历 xml。

    $.get('data.xml',function(xml){

     var jsonString = $(xml).find('vehicleJson').text();
     console.log(jsonString);

     var parsedObj = JSON.parse(jsonString)
     console.log('Description =' ,parsedObj.Description);

  });
