Google sitemap + auto keyword generator in one?

I would like to know if there are any scripts out there at automatically scans my site for keywords by the uploaders URL, generates the key words then uploads them automatically to google through google sitemap?

Is there an all in one script out there or do I have to add auto keyword generator and google sitemap separate?

Normal XML sitemaps can’t contain keywords.

Are you talking about image sitemaps and video sitemaps? (Which can contain titles etc.)
