使用JavaScript在IE9上获取iframe xml内容

Question

I am having a hard time to get the xml content of my iframe on IE9. On other browser, it is working well but the way it rendered on IE9 is my problem.

My iframe and it's content rendered on IE9:

<iframe name="myiframe' id="myiframe">
    <Namespace xmlns:xsd="http://www.w3.org/2001/XMLSchema">
        <Nodes>
            <node>
            <node>
        <Links>
    ........

The code that I use to get the content:

var iframe: HTMLIFrameElement = <HTMLIFrameElement>document.getElementById('myiframe');
var xml = iframe.contentWindow.document.firstChild.textContent;

When I tried to alert the xml , it is displaying only the content of the node, not including the node title, even the < and > .

I need the xml string value. Any thoughts?

Actually that is invalid as per your markup, you have put the nodes between the opening/closing of iframe and that only executes if any browser doesn't support iframes. An example of iframe @MDN

Also getting text content from iframe is also actually depends on Same origin policy .

.textContent is doing correct thing to get the text of the element you are targeting. If you want to get the html/Node of the element you are targeting then you should use outerHTML :

var xml = iframe.contentWindow.document.firstChild.outerHTML;
