title: Latitude/Longitude Regular Expression
body: <p>I'm in the middle of developing a Twitter app. While parsing JSON I need to extract latitude and longitude, store them in a database and then later use them in an Android app. Basically, I managed to extract it, but people are sending their tweets from different devices (iPhones, Blackberries, etc.). I'm getting different responses. Here are the examples:</p>
  
  <pre><code>ÜT: 51.554644,-0.003976
  51.576100, -0.031600
  Iphone: 51.554644,-0.003976
  </code></pre>
  
  <p>Now my question is: how can I use a regular expression to match latitude and longitude and extract it in a form of array in JavaScript regardless of the word that appears in front of it?</p>
