title: Get json value without string prefix
body: <p>I have a json like this:</p>
  
  <blockquote>
    <p>var x = {"foo:bar":"xyz"};</p>
  </blockquote>
  
  <p>I can get xyz by call x["foo:bar"] but is there anyway to get xzy by calling just bar and remove the foo prefix? something like x["bar"]? The json is converted from xml with namespace like that, I can't change it. Thanks</p>
