Printing xml data

Question

Hi,
I am wondering why System.out.println has changed its behaviour in 1.5.0_02.
This is my test code:
import org.xml.sax.*;
import org.xml.sax.helpers.DefaultHandler;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
import javax.xml.parsers.SAXParserFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.FactoryConfigurationError;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.w3c.dom.DOMException;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import java.io.*;
public class test
static Document document;
public static void main(String argv[])
if (argv.length != 1) {
System.err.println("Usage: java teszt filename");
System.exit(1);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
FileOutputStream out;
PrintStream print;
//factory.setValidating(true);
//factory.setNamespaceAware(true);
try {
DocumentBuilder builder = factory.newDocumentBuilder();
document = builder.parse( new File(argv[0]) );
Node root = document.getDocumentElement();
System.out.println("root " + root);
catch (SAXParseException spe) {
// Error generated by the parser
System.out.println("\n** Parsing error"
+ ", line " + spe.getLineNumber()
+ ", uri " + spe.getSystemId());
System.out.println(" " + spe.getMessage() );
// Use the contained exception, if any
Exception x = spe;
if (spe.getException() != null)
x = spe.getException();
x.printStackTrace();
} catch (SAXException sxe) {
// Error generated during parsing)
Exception x = sxe;
if (sxe.getException() != null)
x = sxe.getException();
x.printStackTrace();
} catch (ParserConfigurationException pce) {
// Parser with specified options can't be built
pce.printStackTrace();
} catch (IOException ioe) {
// I/O error
ioe.printStackTrace();
} // main
After compiling and running it with an input xml file I get the output:
D:\Dokumentumok\Irodalom\Java\teszt>java test test.xml
root [ictrl: null]
(Previously I got the whole document)
Can anyone help me why this happens?
Thanks in advance

This is not a change in behaviour for println(), but for the used XML API probably because Java 1.5 is using a new implementation (Xerces 2).
System.out.println("root " + root);The root.toString() method is obviously not returning what you are expecting it to do. There must be some other method to dump the entire tree. or you need to traverse it manually to print out each node. Check the xerces docs for the Node class.
