title: I'm using Intellij IDEA. How do I "view source" for xerces stacktrace that is used by scala.xml?
body: <p>I have to debug a project that uses scala.xml from Scala 2.8.1. A bug that I have presents the following stacktrace (irrelevant parts omitted):</p>

  <p>I'm using Intellij IDEA and I would like to click on the stacktrace line and go to the source even in the lines that currently say "Unknown Source".</p>
  
  <p>Note that:</p>
  
  <ul>
  <li>the XML file that gives the error is valid (and big)</li>
  <li>I only call XML.loadString after obtaining the content of the file</li>
  <li>I don't mind doing something that escapes IDEA realm if you have a different "idea". :)</li>
  </ul>
