There are gov't data files: http://www.cdc.gov/EpiInfo/
Available in this weird SAS format. How can I convert them into XML/CSV, something much simpler that can be read by scripts/etc.???
I had the same problem, so i made a simple SAS data viewer. You download it from the downloads section here: http://code.google.com/p/sasquatch
It has alot of the same features as SAS Universal Viewer, but its still a work in progress.
You need to have Adobe AIR installed, you can get that on the adobe website.
