title: Error about invalid XML characters on Java
body: <p>Parsing an xml file on Java I get the error:</p>
  
  <p><code>An invalid XML character (Unicode: 0x0) was found in the element content of the document.</code></p>
  
  <p>The xml comes from a webservice.</p>
  
  <p>The problem is that I get the error only when the webservice is running on localhost (windows+tomcat), but not when the webservice is online (linux+tomcat).</p>
  
  <p>How can I replace the invalid char??
  Thanks.</p>
