I've worked with some scripts as html, css and php, but now I have something that I don't know what kind of script I have to use.

I want to load data or (rss) feed about the weather from somewhere up-to-date. If this feed says it's going to rain, i want my webpage to load several things like a text which says it's going to rain, a button with a link and some rain drops which will probly be made in a transparancy flash layer.

So i need a script which loads feed, which sees if it is going to rain or not and which can load several things when it is going to rain and leave these things if it is not going to rain.

I hope someone can give me some advice about which kind of script, like java or something else. And maybe some more specific, so i know what to look for.

Thanks a lot!
