I am researching at google for hrs, but tend to not find anything :/

how do i create rss.xml for my wordpress blog?

I don't mean feed://www.blabla.com/blog/feed/ ! I want the posts insxml format. how do i create such .xml for my wordpress posts?

I want http://www.blabla.com/blog/rssfeed.xml

NOT feed://www.blabla.com/blog/feed/

For instance msnbc has such file http://rss.msnbc.msn.com/id/3032091/device/rss/rss.xml

Thanks!

You need to add exterior Nourishes to wour Wordpress blog? WordPress › FeedWordPress « WordPress Plugins

Pay attention to what others listed here are suggesting. Your WordPress site provides XML with the /feed url in your site. When the admin from the other website is suggesting it will not work then look for a far more knowledgeable person on that finish to complete the implementation.
