XML Validation using JAVA

[Former Member]

Hi,

I have a JAVA program:

package dTDValidate;
import java.io.*;
import org.w3c.dom.*;
import org.xml.sax.*;
import javax.xml.parsers.*;
import javax.xml.validation.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.stream.StreamResult;

public class DTDValidateXML {
	public static void main(String args[]) {	
		try{
			DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
			factory.setValidating(true);
			DocumentBuilder builder = factory.newDocumentBuilder();
			builder.setErrorHandler(new org.xml.sax.ErrorHandler() {
				//Ignore the fatal errors
				public void fatalError(SAXParseException exception)throws SAXException { }
				//Validation errors 
				public void error(SAXParseException e)throws SAXParseException {
					System.out.println("Error at " +e.getLineNumber() + " line.");
					System.out.println(e.getMessage());
					System.exit(0);
				}
				//Show warnings
				public void warning(SAXParseException err)throws SAXParseException{
					System.out.println(err.getMessage());
					System.exit(0);
				}
			});
			Document xmlDocument = builder.parse(new FileInputStream("Employee.xml"));
			DOMSource source = new DOMSource(xmlDocument);
			StreamResult result = new StreamResult(System.out);
			TransformerFactory tf = TransformerFactory.newInstance();
			Transformer transformer = tf.newTransformer();
			transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, "Employee.dtd");
			transformer.transform(source, result);
		}
		catch (Exception e) {
			System.out.println(e.getMessage());
		}
	}
}

I have some queries about the above code:

I have output structure as:

<Receivers>

<Receiver>

<Party>

</agency>

</scheme>

</Service>

</Receiver

</Receivers>

1) What modification should be made to the above code to ensure so that the correct Receiver Service is populated by the above JAVA code as per the output.

For example:

If no validation error, Service should be Service1

If validation error, Party should be Party1 and Service should be Service2

Please help.

Thank you,

Pankaj.
