Current surfing conditions lamp - via RSS feed

Hi im new to Arduino but am hoping to use it to create an idea i have using the UNO rev 3

I would like to be able take an RSS feed from here http://magicseaweed.com/syndicate/rss/index.php?id=2&unit=uk and use the star ratings value to control an LED so…

1-2 stars would switch on a blue LED
3-4 stars would switch on a green LED
5 stars would switch on a red LED

Or even better would be the ability to drive a LCD matrix that would return a text value based on stars so…

1-2 stars would say ‘The surf is shit’
3-4 stars would say ‘The surf is good’
5 stars would say ‘The surf is pumping!!’

Im hoping to use/hack the code here as a starting point,http://www.adafruit.com/forums/viewtopic.php?f=31&t=27003 as im very new to Arduino i thought it would be a good idea to check here that its feasible.

Thanks
Al

You'll need a network interface of some sort. Once you have that, reading an RSS feed shouldn't be hard. Lighting LEDs or displaying text on a LED or LCD display are both well known problems.
