Javascript - XML Response Headers

I want to be able to extract information from the header of an xml file. I’ve managed to do GET and POST by downloading and accessing the xml file but I need to access it from a web service.

I can’t find the ability to do this using the www class an I don’t particularly want to go down the uniweb route.

Is it possible to do this natively using javascript in Unity?

Thanks in advance.

I don’t think so - the WWW class really sucks, and beyond that, its behaviour is quite different on different platforms. Best avoided unless you really must use it.
