Arduino getting text from webpage through ethernet sheild to display on lcd

Hey i was wondering if anyone could give me guidance on what this is called for instance getting todays temperature from a weather website and to display the result on the lcd of the arduino but for the arduino to do this independently without a PC connected to it. Is this possible.

I see it being a feasable idea as i know that RSS feeds can be displayed on the LCD pannel.

Im in such a muddle, please help
