I finally got this working. Setting the content-type did the trick (thanks
Diez). Now when I invoke the url directly in the browser I get an xml
formatted page in response. With regards to the parameter segVal, the way I
show it in my example works (XMLHttpRequestObject.open('GET',
"${tg.url('/sponsor/getDivisions/" + segVal + "')}");) because it gets
passed to the (python) controller in order to query the database, and not
sent to a html page which would require ".../?segmentid=" + segVal + "...".
Although the xml method is working, it seems from what I have read that json
would be a better way to handle it. To convert the data to json in the
controller, is it just a matter of formatting it with the curly brackets
etc. ({"foo" : "bar" }), or do I need to use some other functions for the
conversion? And do I need to include @expose('json')?
Thanks.
