title: Accessing an object element containing a colon in js
body: <p>I parsed some xml into json, using xml2js and got elements containing colons:</p>
  
  <pre><code>obj = { "data:example":"smthing"};
  </code></pre>
  
  <p>Do you know a way to access these elements straight from json ?
  Or any tricks maybe ?</p>
  
  <p>Thank you !</p>
