XPATH is too slow for me, I really gave it a fair try in my AJAX applications.

JSON is not just string manipulation, it is a subset of the literal object notation of JavaScript. I think JSON doesn't make very much sense in other programming languages, but hey we're talking JavaScript now.

I think this is a really great and fast way to get data from the server:

var responseDataObject = eval(xmlHttp.responseText);
