title: For constrained devices, is JSON better than XML to transmit data between devices?
body: <p>When we look at a pure JSON or XML document of same information, XML tends to be slightly bigger because it contains opening/closing tags.</p>
  
  <ol>
  <li><p>In this sense, for constrained devices (with super-small flash memory: e.g. 32KB), is JSON better than XML to transmit data between devices?</p></li>
  <li><p>Or, are there any more aspects that I have to take into account apart from document size?</p></li>
  </ol>
  
  <p>Thank you very much in advance.</p>
