XMLHttpRequest之后的innerHTML无法在IE9上运行

Question

I have the following black of code which is working perfectly fine on Chrome & Firefox but fails everytime on IE, it returns "undefined" in the console tab. 我有以下黑色代码，它们在Chrome和Firefox上运行正常，但每次在IE上均失败，它在控制台选项卡中返回“未定义”。

<html>
<head>
    <script type="text/javascript" charset="utf-8" src="/js/jquery-latest.js"></script>

<script>
$(document).ready(function()
{

test(); 

});


function test()
{

          if (window.XMLHttpRequest)
          {// code for IE7+, Firefox, Chrome, Opera, Safari
          xmlhttp=new XMLHttpRequest();
          }
        else
          {// code for IE6, IE5
          xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
          }
        xmlhttp.open("GET","/xml/products.xml",false);
        xmlhttp.send();
        xmlDoc=xmlhttp.responseXML;
        var list = xmlDoc.getElementsByTagName("product");
        console.log(list[0].childNodes[1].innerHTML);

}
    </script>
</head>
</html>

The XML i'm using is the following : 我正在使用的XML如下：

Thanks for your time. 谢谢你的时间。

EDIT: jQuery ajax version not working either: 编辑：jQuery ajax版本不能正常工作：

var xmlDoc;     
$.ajax({
    type: "GET",
    url: "/xml/products.xml",
    dataType: "xml",
    success: function (xml) {
        xmlDoc = xml;
                var list=xmlDoc.getElementsByTagName("product");
                console.log(list[1].childNodes[1].innerHTML );
    }
});

No idea why this works in Chrome and FF, it shouldn't actually ¹ . 不知道为什么在Chrome和FF中可以正常工作，实际上不应该¹ 。

You are loading an XML document, and are successfully selecting an XML element node. 您正在加载XML文档，并成功选择了XML元素节点。 Those don't have innerHTML properties ² . 那些没有innerHTML属性² 。 You should use an XMLSerializer if you really need to get the markup of your xml document (maybe you're just looking for the .textContent ?). 如果确实需要获取xml文档的标记，则应该使用XMLSerializer （也许您只是在寻找.textContent吗？）。

var el = list[0].childNodes[1];
console.log(new XMLSerializer().serializeToString(el));

However, oldIE doesn't even know that, you'll need to use el.xml for them ³ . 但是，oldIE甚至不知道，您需要为它们使用el.xml ³ 。
