我正在尝试获取句柄项以便稍后使用这些数据。但是，第五项似乎失败了。当我这样做时：

var xml = new XMLHttpRequest();

xml.onreadystatechange = function ()
{
   if(xml.readyState == 4)
   {
      var xmlDoc = xml.responseXML;
      if(!xmlDoc)
      xmlDoc = (new DOMParser()).parseFromString(xml.responseText, 'text/xml');

      var handle_list = xmlDoc.getElementsByTagName("handle");

      console.log(handle_list);
   }
}

我在控制台中收到了这个：

[handle, handle, handle, handle, handle, item: function]
0: handle
1: handle
2: handle
3: handle
4: handle
length: 5
__proto__: NodeList

此外，日志中索引4处的项目不完整。我在这里做错了什么？

我正在添加我的评论作为答案，因为它似乎是您可以将此问题标记为已回答的答案。

标签周围的xml文件中有一个未转义的＆符号解析器停止。也许这是你问题的原因？

XML getElementsByTagName在中途退出
