Need xml driven weather component in the intranet

I want to know if there's a free xml driven weather component开发者_如何学编程 (flash or other) to display weather in my intanet site.

All the components I've found use online rss feed. Is there a component that supports update in offline mode (manually).

Thanks in advance

I don't know of an existing library, but why don't you just create your own RSS feed (it's a simple XML file) and update the data manually?
