You need to use  in your link. By defaul, the API uses a HTML representation of XML, and therefore cannot be treated as XML unless a format is specified. In addition, although it seems to work, i'd recommend using  to executing whatever script is based on the result.

Also, i doubt if there are enough people who go on wikia who still use IE5 or IE6 to bother for adding support to them, but i guess it cannot harm.
