title: How to show line numbers on an XML file
body: <p>Say I have this XML file: <a href="https://prod-c2g.s3.amazonaws.com/db/Winter2013/files/courses-noID.xml" rel="nofollow noreferrer">https://prod-c2g.s3.amazonaws.com/db/Winter2013/files/courses-noID.xml</a></p>
  <p>Is there a way to show the line numbers on the web page or do you have to copy to <a href="https://en.wikipedia.org/wiki/Eclipse_%28software%29" rel="nofollow noreferrer">Eclipse</a> to show the line numbers?</p>
  <p>I want to avoid copying to Eclipse because then I cannot expand or minimize tags.</p>
