title: How to unmarshal <!DOCTYPE> section In JAXB?
body: <p>I need to unmarshal <strong>!DOCTYPE</strong> section using JAXB so I can get the values of file1 and file2.</p>
  
  <p>The xml file looks like this  :</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  
    &lt;!DOCTYPE doc [
       &lt;!ENTITY file1 SYSTEM "conf/files/file1.xml"&gt;
        &lt;!ENTITY file2 SYSTEM "conf/files/file2.xml"&gt;
      ]&gt;
  
      &lt;appels&gt;
        &lt;appel&gt;
           &amp;file1;
        &lt;/appel&gt;
        &lt;appel&gt;
           &amp;file1;
         &lt;/appel&gt;
      &lt;/appels&gt;
  </code></pre>
  
  <p>the java look like this : </p>
  
  <pre class="lang-java prettyprint-override"><code>@XmlRootElement(name = "appels")
  public class Appels implements Serializable {
  
  private List&lt;Appel&gt; appel;
  
  }
  </code></pre>
  
  <p>I need to get 
  file1 = conf/files/file1.xml <strong>and</strong> 
  file2 = conf/files/file2.xml</p>
  
  <p>is this possible?
  Thank you for the help </p>
