I don’t usually post software links, but KeneticFusion by Kenesis Software is very cool. It allows you to decompile a swf into xml or compile xml to a swf. This may not seem like a big deal to some, but this software is so far along and is free. It decompiled a large swf/project that I did a while back without a hitch.
Some other things to note:
1. The documentation is there with a bunch of samples
2. There is work underway to develop an xml Schema
3. This might be an answer to some people who want to be able to version control their projects (including Fla’s). Since your project would be xml based, you could have CVS keep a record of all the changes!
4. ItÂ’s just cool!
