Working with xml in Actionscript 3.0

I dont know where I read this, and correct me if Im wrong, but does actionscript 3.0 have a very different way of working with xml ? I heard it was made “easier” or “simpler” to navigate xml documents and work with it in general…how much of this is true? is it true? what is the new way of working with xml like ?

Thanks as always !!!
