title: Compare to current date
body: <p>I have a xml file with rows like this :</p>
  
  <pre><code>&lt;Data&gt;
      &lt;a&gt;something&lt;/a&gt;
      &lt;b&gt;20120601&lt;/b&gt;
      &lt;c&gt;something else&lt;/c&gt;
  &lt;/Data&gt;
  </code></pre>
  
  <p>the value in  is a date formatted YYYYMMDD</p>
  
  <p>I have a small template that processes each row, and which is working fine (for it doesn't do much)</p>
  
  <p>Now my question :
  How can I process a row only if the date in B is greater (later) than 60 days before today (current date) ?
  So if the date is recent -> process the row, else don't.</p>
