Yahoo Weather Forecast parser

http://developer.yahoo.com/weather/
|

This sketch demonstrate how to use the Linux command line tools
|
||||
to parse a simple XML file on the Arduino Yún.
|
||||
|
||||
First thing download the XML file from the Yahoo Weather service
|
||||
than use "grep" and "cut" to extract the data you want.
|
||||
|
||||
To find the location ID of your location, browse or search for your
|
||||
city from the Weather home page. The location ID is in the URL for
|
||||
the forecast page for that city.
