问题
My website is broken in IE11. We found that it’s broken due to XSLTProcessor and XPathEvaluator since they are not supported any more in IE. I did some R&D and found that it’s also not supported in IE9 and IE10 but my website is working fine in IE9 and IE10. May I know why it is broken in IE11?
In below screenshot, we can see that document mode is Quirks. Don’t we have same behavior for IE11?

EDIT
We also have meta tag in our master page and it was working fine until IE10 but it’s broken in IE11.
<meta http-equiv="X-UA-Compatible" content="IE=8" />
Do we have to use different meta tags for IE11?
回答1:
I changed meta tag to <meta http-equiv="X-UA-Compatible" content="IE=5" />
and it started working fine.
