You have to

  1. create background task

  2. gather the XML or JSON data and parse it (from the internet) and then put that data into the ‘contentNode’ of whatever object you are rendering. Final step is to set the contentNode of your component equal to the contentNode containing all of your gathered data.

this is quite a complex all-in-one example …
