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.

You can read some detailed info about the content contained in the RSS file here.
