title: How to compare 10 big XML files?
body: <p>I have 10 big XML files and some files are different from others (it represents data in a step of the process).</p>
  
  <p>How to compare them <strong>AUTOMATICALLY</strong>?</p>
  
  <p>I do know I can compare them manually using tools like <a href="http://en.wikipedia.org/wiki/WinMerge" rel="nofollow">WinMerge</a> or eyes, but I don't like that approach.</p>
  
  <p>I would like it to do it on a Windows machine, but I have <a href="http://en.wikipedia.org/wiki/Cygwin" rel="nofollow">Cygwin</a> installed.</p>
  
  <p>I think I can somehow use <strong>git diff</strong> to do that, but ... how?</p>
