How to Set Up the XML Parser

You have now created the networking and XML generation code for the application. The CrnpClient constructor calls a setupXmlProcessing method. This method creates a DocumentBuilderFactory object and sets various parsing properties on that object. The JAXP documentation describes this method in more detail. See http://java.sun.com/webservices/jaxp/.

1. Create the Java code that implements the preceding logic.

   private void setupXmlProcessing() throws Exception
   {
           dbf = DocumentBuilderFactory.newInstance();
   
           // We don't need to bother validating
           dbf.setValidating(false);
           dbf.setExpandEntityReferences(false);
   
           // We want to ignore comments and whitespace
           dbf.setIgnoringComments(true);
           dbf.setIgnoringElementContentWhitespace(true);
   
           // Coalesce CDATA sections into TEXT nodes.
           dbf.setCoalescing(true);
   }
