Answer 1

You cannot open a local file directly in a Flex app. You have to upload it to the server and load the contents from there. This code will upload it to the server.

var file:FileReference = FileReference(event.target);
file.upload(uploadURL);

Answer 2

Try:

tree.dataProvider = new XMLListCollection(XMLList(XMLDP));
