BTW, Internet Explorer does not support XHTML. Please leave an attribution line for each included quotation level.

What and where to add? Nothing really. I just recalled another oops for local files: responseXML gets triggered and filled only if XML data is served with the proper Content-Type like "text/xml", otherwise responseXML remains empty. As you cannot send Content-Type for local file, you get no data into responseXML. Read responseText instead - your data is in there, but as text/plain of course. I do recall some enforceContentType or something for request, but honestly I would just take a time verified AJAX library rather that reinventing the wheel and hitting all per browser and per situation bizarrities.
