Yes, that's the problem. In Flash, xml loading is always asynchronous so the
trace line is executed immediately after the previous one, in which you
created an instance of retornaXML; so the XML object isn't at that point
loaded and parsed. (It would perhaps be nice to have the option of loading
synchronously, but I digress...).
So, you'll have to listen to the COMPLETE event dispatched by the URLLoader
and then access the xml object.
You can wrap your xml and the loading logic in a custom class as you seem to
be doing so far, but if you're just going to load the xml and the read it /
parse it somewhere else (outside that class), in my humble opinion, the
wrapper is pointless.
You'll end up re-dispatching the Loader events (all the events you want to
support; the error events, and the complete event, at least, just in case
something went wrong, and perhaps the Progress event as well) so your
external code can handle the different scenarios. By the time you are done
coding that, you'll find that you have a class that does almost nothing of
use by itself; it just copies all the functionality that you already had in
the URLLoader and XML classes out of the box. I did it a couple of times
when I started to use AS 3.0, but I changed my approach as it didn't make
much sense to me to have such a class. Having all that logic encapsulated in
the class that actually does something with the xml, on the other hand,
seems like a good idea to me.

Thanks for your answer. But how? Where?. I think that
ProgressEvent.bytesLoaded, and ProgressEvent.bytesTotal could help. But
where should I check the status?

you could use an event to listen to, to pass the XML out of the class.
