title: How do I find errors in a XML file?
body: <p>Sometimes when I'm trying to run my code, the Eclipse console says:</p>
  
  <blockquote>
    <p>Error in an XML file: aborting build.</p>
  </blockquote>
  
  <p>That means that I have a mistake in my main XML file. Is there any way to find my mistake without making guesses and erasing some XML code in order to see where the problem is? Something like validation of my XML file! Thanks.</p>
