I wrote this little PHP code. It is not a contribute just something I wrote up really quick to submit to the Bing product feed.
I attached the file. Just open it up in an editor and fill in your information. I would rename the file to something no one would guess since it will have your MySQL info in it or even place it on the server then remove it once you've made the file. If you do leave it there you can run a cron job so it stays updated.
Right now it includes all your product, whether it is inactive or not. If you know how to code it would be easy to include a conditional and load the product active data, I just don't have time and all my products are current.
Enjoy everyone, glad I could offer something.
