[SOLUTION] Current Temperature (#68

Rudolfs Osins

Hello everyone !

Here is my solution, actually it's my first ruby program, I just
started learning... Suggestions on how to improve my code are
welcome :)

This is how it looks when executed, I couldn't find where to turn
these warnings off :/

------------------------------------------------------------------

root@black /# ./weather.rb madrid
ignored element: {http://schemas.xmlsoap.org/...}binding
ignored element: {http://schemas.xmlsoap.org/...}operation
ignored element: {http://schemas.xmlsoap.org/...}urlEncoded
ignored element: {http://schemas.xmlsoap.org/...}mimeXml
ignored element: {http://schemas.xmlsoap.org/...}content
ignored element: {http://schemas.xmlsoap.org/...}address
The temperature in Madrid / Cuatro Vientos is 3 C

------------------------------------------------------------------

#!/usr/local/bin/ruby
require 'soap/wsdlDriver'
require 'rexml/document'

URL = 'http://www.webservicex.net/globalweather.asmx...

# process the comandline arguments
if ARGV[0] == nil
abort("Usage: weather.rb city")
else
city = ARGV.join(' ')
end

soap = SOAP::WSDLDriverFactory.new(URL).create_rpc_driver
begin
weather = soap.GetWeather(:CityName => city, :CountryName => "")

# strip the first line with <? ?> stuff, else REXML wont parse
xml = weather.getWeatherResult.gsub(/(<\?.*?>\n)/, '')
data = REXML::Document.new(xml)

# celsius degrees are in parentheses
data.elements["//Temperature"].text[/\((.*)\)/]; temp = $1
data.elements["//Location"].text[/^(.*),/]; loc = $1

# show the gathered data
puts "The temperature in " + loc + " is " + temp
rescue
puts "Could not find data for your supplied city: " + city
end

------------------------------------------------------------------

Best regards,
Rudolfs

$-w = nil should work.

Actually, I tried to use this webservice too, but I got so mad at it
and it's freaking dumb semantics that I dropped that for health
reasons. Looks like you did it, though. ;-)

Yay, that works, no warnings anymore :) Where can I read more about this magic
$-w variable ?
