Hi.
Extracting the symbols from a SWF is a little bit involved as it requires low level development. Fortunately there are a few libs around that seem to be able to do this, like https://github.com/Flassari/Swf-Class-Explorer, from Flassari. So I did a little AIR for desktop app that is able to navigate for a folder containing SWFs and listing their symbols using the lib above. Not sure if it's what you want, but I hope it at least helps you to get started. AS3 code:
