It's not hard with e4x: Let's say your arrayCollection (myAC) items have three properties... ID, Name and Address. Here's the code:
myXML:XMLList = <Users/>
for each (var item:Object in myAC) {
myXML += <User ID={item.ID} Name={item.Name} Address={item.Address};
}
Not checked for validity, but you get the idea.
