YouTube Video Data in MySQL DB with PHP

We have a youtube account (will be given to a bid winner) I want following to be developed. I want to generate XML Video sitemap based on details stored in MySQL database via php & xml (if needed) Currently we have around 140 videos on our youtube channel. What you require to do - 1. Gather ALL video details from YouTube (automatically through PHP and XML if needed) 2. Insert into MySQL table (already created) 3. Fetch data from MySQL and display it on a web page (with simple SELECT statement - just for viewing purpose to know ALL videos have been listed) 4. Fetch data from MySQL and generate an XML file (in a sitemap format) and save it on server OR If you want to genearate XML file directly using YouTube API or RSS feed. No problem. Bottom line is to generate XML sitemap file which i can use and submit as a sitemap for videos. Thats it. Format i require, is attached. See attachment. Any questions, please feel free to ask here. Thanks.
