HI THERE,

I have a strange problem. I am writing a firefox extension to the
Onlywire API (http://onlywire.com/index?api). Now the problem is when
I tag pages using the onlywire API the service responds with an xml
that indicates whether the web page was tagged successfully.
Something like this:

<?xml version="1.0"?>
<result code="success" />

Now using the api requires http authentication. After the
authentication succeeds the service responds with an xml file. Now,
the problem is that I dont want the users to see this xml file, I want
to somehow parse the xml file that I receive and display appropriate
message in a popup box.

Any help would be just great. Thanks.

Cheers.

You can use XMLHttpRequest
<http://www.xulplanet.com/references/objref/XMLHttpRequest.html> to make
the request, the open method takes username and password as optional
parameters and you can use the responseXML object to access the XML sent
as the response.

If I understand correctly, I don't think XMLHttpRequest is suitable
here, because it looks like the submission is always done to www.onlywire.com
(another domain).

Since the sandbox model doesn't allow access to this XML response, I
think the only possibility is to perform the request from a server
script. And then parse the response at server before returning output
to client.

The original poster is writing a Firefox extension and not some script
in a web page.

I don't have any experience in those, but wouldn't XMLHttpRequest need
to go to the other domain anyhow (namely, to onlywire.com) ? Or is it
possible to grab URL's from remote servers with XMLHttpRequest in
Firefox extensions ?

I know of no restrictions for Firefox/Gecko extensions. There is even a
Firefox extension written in JavaScript that can display the IP address of
the accessed and the accessing host through XPCOM, among other things. [1]
It is very likely that the Same Origin Policy does not apply here.

I would be surprised. Care to backup this claim ?

Have I not just proved that extensions can do more than the average
client-side Web script?

I have not claimed anything, so I have nothing to back up.
