Answer : Adobe Flex: Browse For XML File(FileReference), Modify It, then upload it to server?

FileReference.data 's type is ByteArray so here you'll have to convert the ByteArray to XML.

Possible solution:
------------------
var data:ByteArray = refUploadFile.data as ByteArray;
data.position = 0;
var newXML:XML = XML(data.readUTFBytes(data.length));
------------------------

Hope this will help.
