You can only use flash.filesystem.File in AIR. But you can still load XML files using either HTTPService or URLLoader. Check out this answer which has sample code for loading XML into Flex.

If you get a Security Sandbox Error when trying to load, set the Flex Compiler argument use-network=false, which will allow you to load local files into the swf.
