Best way to dynamically load an xml configuration file into a Flex4/Flash movie at runtime?

I've got a rather simple question about loading in an xml file at runtime in a SWF.

I've found a couple different methods to load in the xml.

• myXml.load("file.xml");
• HTTPService object
• URLStream object

What开发者_如何学Go is better way to load an xml file that always has the same name and is located in the same folder as the SWF on the web server?

I would use URLLoader - I think that's the most lightweight one.

• The complexity of URLStream is unnecessary as far as a configuration file is concerned.
• HTTPService again is heavy for this simple task (and Flex only). Of course, it allows you to get away with minimum code, but I use it only for something that needs to be updated repeatedly (binding the lastResult to a live DataGrid etc).
• myXml.load() - this is not AS3, is it?
