One thing that I do quite often in Flash is load XML. In order to save time, I separated a lot of that code out into external class files. I also created a snippet of code that calls those files in order to save time when I want to use them. (You will need Lee Brimlow’s snippets panel for this to work.)
The LoadXML and LoadURL classes are probably very similar to those found at Learning Actionscript 3 as that is where I learned a lot about this topic previously. Hope you find this helpful!
