  <p>I'm running a nightly cron job that downloads and XML file. The XML file has dates formatted like this:</p>
  
  <pre><code>&lt;date&gt;2011-09-30&lt;/date&gt;
  </code></pre>
  
  <p>I'd like to set up a second cron job that changes each date to be formatted like this:</p>
  
  <pre><code>&lt;date&gt;September 30&lt;/date&gt;
  </code></pre>
  
  <p>and then saves the file.</p>
  
  <p>Is there a good way to do this with a shell script?</p>
