TLF editor for my CMS?

for my flash website, I have several flash text areas using this TLF and I know and love how the markup import/export thing works... the main problem I'm facing is that I don't know how to update my CMS buing built in PHP already?

in the last version which I used htmlText, I used a simple FCK editor in php and it generated the html tags and flash could read and display the text, but with the new markup xml, I'm confused!

so, I thought maybe I could have a flash editor integrated into my CMS so I can write and edit my text in there and when saving, it will export the xml markup and save it into database and the site text areas will use that markup to show the text...

I think this is the best thing to do, but how can I write a flash text editor?! that will certainly take a LOT OF time and I don't have that time! so I'm posting this question here in hope that someone has thought of something? I mean, there must be a standalone editor like the one we have now in flash CS4 > Window > Other panels > Text Layout so that I can put that in my CMS and use its xml markup export thing to save changes to the content...

maybe you have a better solution or something? please let me know. Thanks for any ideas.
