title: Lua string.match pattern for MSN weatherservice
body: <p>I use the <a href="http://weather.service.msn.com" rel="nofollow">MSN weatherservice</a>. Now I have the following problem with <code>string.match</code>. All variables are filled except <code>sWindRichtung</code>. It equals <code>nil</code>.</p>
  
  <pre><code>sHumidity, rest = string.match(rest,"humidity=\"([^\"]+)\"(.*)");
  sWind, rest = string.match(rest,"windspeed=\"([^\"]+)\"(.*)");
  sWindRichtung, rest = string.match(rest,"winddisplay=\"([^\"]+)\"(.*)");
  </code></pre>
  
  <p>The string to filter is: <code>humidity="77" winddisplay="11 km/uur N" windspeed="11"</code></p>
  
  <p>I think that the character <code>/</code> is the problem. </p>
