RE: [flexcoders] XML vs Model?
They are similar things IMO. If you specify a source file for XML or Model tag, source (xml)file is compiled into swf. So no loading on runtime but a large initial swf size.

RE: [flexcoders] XML vs Model?
One of my issues with Model is I had trouble determining how the xml was going to be deserialized into the object. What happens to attributes? What happens to child nodes and text nodes? Since I was comfortable with xml I mostly stuck with that. I haven't even needed the available Xpath library yet. And I hear that improved XML support is on the way.

Re: [flexcoders] XML vs Model?
Performance-wise I find that both to be equivalent. But mx:Model provides a much easier way to access nodes of an xml document (and most of the times, the easier, the better!). But I agree with Matt's observation that mx:XML serves a better dataProvider for the Tree control.

Re: [flexcoders] XML vs Model?
Thanks All! :) I think XML is the best buy for my situation but will keep the above opinions in the back of the mind for future use.
