# Allows retrieval of current temperature information. Pretty simple
# and straight forward. Uses match to extract data from the xml
document
# that is returned. Sorry about the long lines, but I like putting as
# much code in one line as possible.
#
# usage: ruby current_temp.rb [zipcode|other]
#
# zipcode: US zipcode
# other: country code information. example: SPXX0050 for Madrid,
Spain

require 'net/http'

begin
weather_info = Net::HTTP.get( "xml.weather.yahoo.com",
"/forecastrss?p=".concat( ARGV[ 0 ] ) )
print "The temperature in ", weather_info.match( /Yahoo! Weather
for (.*)</ )[ 1 ], " is ", weather_info.match(
/<yweather:condition.*temp="(\d+)"/ )[ 1 ], " degrees ",
weather_info.match( /<yweather:units temperature="(.)"/ )[ 1 ], ".\n"
rescue
print "Information for ", ARGV[ 0 ], " was not found or
unavailable."
