title: How to catch AssertPathsEqual and print error to console?
body: <p>How could I catch this AssertionFailedError and print to the console an message that says:</p>
  
  <p>"Expected text value '55555' but was '55556' at /xpathResult[1]/result[2]/field[1]/field[1]/field[6]/text()[1] for [testFileName] and [testName]"</p>
  
  <p>I'm not exactly sure how to catch the values out from the assertion without having to "hack" and manually parse the diff output string. I would rather have an elegant method rather than a "hack" method.</p>
  
  <pre><code>junit.framework.AssertionFailedError: org.custommonkey.xmlunit.Diff
  [different] Expected text value '55555' but was '55556' - comparing &lt;field ...&gt;55555&lt;/field&gt; at /xpathResult[1]/result[2]/field[1]/field[1]/field[6]/text()[1] to &lt;field ...&gt;55556&lt;/field&gt; at /xpathResult[1]/result[2]/field[1]/field[1]/field[6]/text()[1]

  <p>Am I going to have to write my own DiffDescriber class that parses the Diff text output?</p>
