Question

我正在读取XML文件中的数据，并希望使用angularjs进行编辑。问题是，$http调用是读取数据但是将其转换为字符串，我是否期望它是对象。我的XML数据是：

<?xml version="1.0" encoding="UTF-8"?>
<catalog>
   <book id="bk101">
      <author>Gambardella, Matthew</author>
      <title>XML Developer's Guide</title>

      <check4/>

      <string name="connect_timeout"></string>

在angularjs中使用以下代码：

$http({
            url: "books.xml",
            method: "GET",          
            headers: {'Content-Type': 'application/xml','charset' : 'utf-8'}
        }).success(function (xml) {
                    console.log(xml);
                    console.log(typeof xml);
        }).error(function () {
                    console.log('error in /writexmlfiletest ');                                         
        });

它在控制台中打印数据，typeof显示字符串。请帮忙理解。我是否必须转换回XML以执行节点元素操作？

我们必须将transformResponse放在$ http请求中，如下所示。它将数据解析回xml。

$http({
            url: "books.xml",
            method: "GET",          
            headers: {'Content-Type': 'application/xml','charset' : 'utf-8'},
            transformResponse : function(data) {
                // string -> XML document object
                return $.parseXML(data);
            }
        }).success(function (xml) {
                    console.log(xml);
                    console.log(typeof xml);
        }).error(function () {
                    console.log('error in /writexmlfiletest ');                                         
        });

angularjs从xml文件加载数据并存储在xml对象中
