title: XML vs YAML vs JSON for data feeds in perl application?
body: <p>Assuming I'm starting a project from scratch, which is not dependent on any other project.
  I would like to use a format to store feeds, something like XML, since XML is not the only available format of its kind, I would like to know: why should I choose one over the rest?</p>
  
  <p>I will be using perl.</p>
  
  <p>'Feed' is a description of a product (name, price, type, short description, up to 120 words).</p>
