File types bangle can read/parse?

Hello

I am writing a clock face which will show cricket scores. I currently have the layout sorted with a working clock and date. The scores are hard coded and drawn from source at the moment. Eventually when the android app integration can do internet access it will hopefully update automatically. The next step is to manually add a file to storage for the app to parse.

My question is what types of file can be read? Obviously json but can it read XML or HTML?

Many thanks
Pete
