title: Modify web.xml using Ant
body: <p>Is there any way to strip elements out of a web.xml file using ANT? </p>
  
  <p>For example I have certain servlets I use for Unit Testing defined in the web.xml that are unnecessary in the production environment is there a way to strip these out or do I need to have a separate production web.xml file?</p>
  
  <p>Thank You.</p>
