Angular x2js xml 未定义

Question

我正在尝试让this example 使用 xml 作为 json 数据。但是我对这些代码有些问题。

courses  = x2js.xml_str2json(data);
console.log(courses.books.course);
$scope.todos =courses.books.course;

在示例的 xml 中。有书籍和课程标签。但我不明白“课程”从何而来。

我正在尝试用这个 xml 示例做同样的例子

<diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1">
 <DocumentElement xmlns="">
  <semt_kodlari diffgr:id="semt_kodlari1" msdata:rowOrder="0">
   <semt_adi>ALTIKAT</semt_adi>
  </semt_kodlari>
 </DocumentElement>
</diffgr:diffgram>

这是我的 HTML 部分：

X = x2js.xml_str2json(data);
console.log(X.DocumentElement.semt_kodlari);
$scope.todos = X.DocumentElement.semt_kodlari;

当我运行此代码时，出现“无法读取未定义的属性 'semt_kodlari'”错误。那么有人可以告诉我我的代码有什么问题吗？课程和课程的区别是什么？

我认为您只缺少对象的一个​​父对象。如果您将diffgram 添加到您的console.log，它应该会按预期工作。

查看下面的演示或jsfiddle。

        var todoApp = angular.module('todosApp', []);

        todoApp.factory('todoFactory', function ($http) {
            var factory = {};

            factory.getTodos = function () {
                return $http.get("http://cdn.rawgit.com/motyar/bcf1d2b36e8777fd77d6/raw/bfa8bc0d2d7990fdb910927815a40b572c0c1078/out.xml");
            }

            return factory;
        });
        todoApp.factory('getXMLDataFactory', function() {
            
            var x2js = new X2JS(),
                //xml ="<MyRoot><test>Success</test><test2><item>val1</item><item>val2</item></test2></MyRoot>";

                xml = '<diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1">'+
 '<DocumentElement xmlns="">'+
  '<semt_kodlari diffgr:id="semt_kodlari1" msdata:rowOrder="0">'+
   '<semt_adi>ALTIKAT</semt_adi>'+
  '</semt_kodlari>'+
 '</DocumentElement>'+
'</diffgr:diffgram>';
            console.log(xml, x2js);
            
            return {
                get: function() { 
                    return x2js.xml_str2json(xml);
               }
            };         
        });
        todoApp.controller('todosCtrl', function ($scope, todoFactory, getXMLDataFactory) {

            $scope.todos = [];
            //loadTodos();
            loadData();
            
            function loadTodos() {
                todoFactory.getTodos().success(function (data) {
                    console.log(data);
                    courses = x2js.xml_str2json(data);
                    console.log(courses.books.course);
                    $scope.todos = courses.books.course;
                });
            }
            
            function loadData() {
                console.log('test');
                $scope.todos = getXMLDataFactory.get()
                    .diffgram.DocumentElement.semt_kodlari;
                console.log($scope.todos);
            }
        });
