Error handling in parsing XML files.

Question

Hi.
Is it possible to handle the error generated by DocumentBuilder elsewhere, as it parses down an XML file? In my test-program, I am parsing (using SAX) an XML file, and testing whether it is valid under a certain schema. If it is valid, I would then generate a console-output tree of the XML file. Otherwise, it would just display the error messages (wherever they are in the XML file).
This is what I have.
import java.io.IOException;
import javax.xml.parsers.*;
import org.w3c.dom.*;
import org.xml.sax.SAXException;
import java.util.*;
public class XMLTester {
    private Document document;
    private boolean state = true;
    public XMLTester() { }
    public static final void main(String[] args) {
        if ( args.length != 1 ) {
            System.out.println("Usage: java XmlTester myFile.xml");
            System.exit(-1);
        String xmlFile = args[0];
        XMLTester xmltester ;
        xmltester = new XMLTester();  
        xmltester.parseFile(xmlFile);
        if (xmltester.isValidXML() ) {
             xmltester.printContents());
    public void parseFile(String xmlFile)/* throws ParserConfigurationException,
                        SAXException, IOException */{
    try {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        factory.setNamespaceAware(true);
        factory.setValidating(true);
        factory.setAttribute(
                  "http://java.sun.com/xml/jaxp/properties/schemaLanguage",
                  "http://www.w3.org/2001/XMLSchema");
           DocumentBuilder builder = factory.newDocumentBuilder();
            document = builder.parse(xmlFile);
    } catch (Exception ex) {
         //ex.printStackTrace();
         state = false;
    public boolean isValidXML() {
         return state;
    //..print-out methods here..
}Thanks!

Nevermind.. I figured it out after a few thoughts.
