Google has released a tool called Swiffy for parsing Flash files into HTML5. This is relevant to web scraping because content embedded in Flash is a pain to extract, as I wrote about earlier.
I tried some test files and found the results no more useful for parsing text content than the output produced by swf2html (Linux version). Some neat example conversions are available here. Currently Swiffy supports ActionScript 2.0 and works best with Flash 5, which was released back in 2000 so there is still a lot of work to do.
