AS3 E4X Rundown is a great introduction and reference to working with E4X in Flex. The author, Roger Braunstien is correct that 75% of E4X makes perfect sense, but it’s the remaining 25% that requires a bit of demystifying. I would imagine that there are some users who feel like that percentage should be a lot higher than 25%! This post covers the basics well then goes on to share some of the tips and tricks in working with E4X. This is one of those great reference articles on a technology that might be a little obscure even to seasoned developers but is definitely worth learning about if not working with.
