This snippet comes from a student question about how to get the temperature from yahoo weather.

You could use this snippet to get lots of additional information based on a zipcode… like latitude, longitude, humidity, wind chill etc… The trickiest part of this code is the Namespace stuff… which I find generally annoying… probably just because I’m not used to it.
