I ran into a really strange issue that only occurs within Adobe AIR applications (AIR 1.5.1/1.5.2). When I create a TextField control, set it’s style, and then assign it HTML text it appears fine.

When Flex 1.5 came out, Christophe Coenraets created a application that allowed you to embed HTML pages in Flex using an IFrame. Since the Flex 2 update, this application has been broken, until now. There is a new updated example created bi Brian Deitte. Get the example and source code at Deitte.com.

Now that is a lot of extra code and some of it, though ignored by the browser, is just code used only by Flex (or Flash). What is needed is a way to clean the code and make it more standard so you can store in the database and use in more places than just Flex. Using RegExp, I created a small function that strips out the invalid code and leaves:
