Hi all, I'm hoping someone can help me with this as i'm a true newbie at all of this stuff.

What i'm wanting to do is get the current temperature for my home town and make it save into a text file and keep it updated every 30 mins or so.

I've found this feed: http://www.wunderground.com/auto/rss_full/global/stations/94821.xml

Any help on what I do next?

Please keep in mind i'm a newbie.

Thanks for your time,
Scott
