Thursday, July 27th, 2006p>Alexander Kirk has written about a problem with XHR, responseXML and document.domain in FireFox:
The responseXML object is useless. You can’t access it, you receive a Permission Denied when trying to access it’s content (e.g. documentElement). Very annoying.
Even stranger that responseText is still readable. What’s the reason for this? Is there some security risk i am unaware of or is it a plain bug?
As the responseText is available there is a pretty simple fix: re-parse the XML, which is kinda stupid and cpu intense if you have a lot of them. (something like: var doc =
(new DOMParser()).parseFromString(req.responseText, “text/xml”);)
