Wrong XML parsing in Java 6.0 , the same code works fine with Java 5.0

Question

I have the following xml data in a file ( C:\_rf\jrebug.xml ) :
<?xml version="1.0" encoding="UTF-8"?>
<rs>
     <data
          input3='aa[1]'
          input4='bb[1]'
          input6='cc[2]'
          input8='dd[7]'
          output2='ee[7]'
          output4='ff[511]'
          output6='gg[15]'
          output7='hh[1]'
     />
</rs>
I have the following code to parse this XML data :
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NamedNodeMap;
import org.w3c.dom.NodeList;
import org.w3c.dom.Node;
import org.xml.sax.SAXException;
import org.xml.sax.ErrorHandler;
import org.xml.sax.SAXParseException;
public class DomParserBug {
     Document dom;
     public void runExample() {
parseXmlFile("C:\\_rf\\jrebug.xml");
          parseDocument();
     private void parseXmlFile(String filename){
          //get the factory
          DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
          //dbf.setValidating(true);
dbf.setValidating(false);
          try {
               //Using factory get an instance of document builder
               DocumentBuilder db = dbf.newDocumentBuilder();
               db.setErrorHandler(new MyErrorHandler());
               //parse using builder to get DOM representation of the XML file
               dom = db.parse(filename);
          }catch(ParserConfigurationException pce) {
               pce.printStackTrace();
          catch(SAXParseException spe) {
               spe.printStackTrace();
          catch(IOException ioe) {
               ioe.printStackTrace();
          catch(SAXException se) {
               se.printStackTrace();
private void parseDocument()
Element docEle = dom.getDocumentElement();
NodeList nl = docEle.getElementsByTagName("data");
if(nl != null && nl.getLength() > 0)
for(int i = 0 ; i < nl.getLength();i++)
Element el = (Element)nl.item(i);
NamedNodeMap attrsssss = el.getAttributes();
for (int ii=0; ii<attrsssss.getLength(); ++ii)
Node attr = attrsssss.item(ii);
System.out.println("Attribute name is =" attr.getNodeName() " AND Attribute value is ="+attr.getNodeValue());
     public static void main(String[] args){
          DomParserBug dpe = new DomParserBug();
          dpe.runExample();
     class MyErrorHandler implements ErrorHandler {
          public void error(SAXParseException e) {
          System.out.println("error : " +e.toString());
     // This method is called in the event of a non-recoverable error
     public void fatalError(SAXParseException e) {
     System.out.println("fatalError : " +e.toString());
     // This method is called in the event of a warning
     public void warning(SAXParseException e) {
     System.out.println("warning : " +e.toString());
The parsed output is :
Attribute name is =input3 AND Attribute value is =aa[1]
Attribute name is =input4 AND Attribute value is =bb[1]
Attribute name is =input6 AND Attribute value is =cc[2]
Attribute name is =input8 AND Attribute value is =dd[7]
Attribute name is =output2 AND Attribute value is =ee[7]
Attribute name is =output4 AND Attribute value is =ff[511]
Attribute name   is  =output6 AND Attribute value  is =hh[1]]
Attribute name   is  =output7 AND Attribute value  is =hh[1]
THE LAST TWO LINES ARE SIMPLY WRONG.
With java 5.0 the last two lines are parsed correctly :
Attribute name   is  =output6 AND Attribute value  is =gg[15]
Attribute name   is  =output7 AND Attribute value  is =hh[1]
I have seen this issue only after I upgraded to java 6.0. I have searched the java 6.0 bug database but there is nothing there.
I have also submitted a bug to the bugdatabase last month but have not heared anything.
Anybody have any clue about this ???
Thanks

Answer 1

I have seen similar issue. I found that if you remove the square brackets from the first line in teh XML file, the last two lines are parsed correctly.
Replace the follwing line : :
Attribute name is =input3 AND Attribute value is =aa[1]
with :
Attribute name is =input3 AND Attribute value is =aa
and the output is CORRECT :
Attribute name is =input3 AND Attribute value is =aa
Attribute name is =input4 AND Attribute value is =bb[1]
Attribute name is =input6 AND Attribute value is =cc[2]
Attribute name is =input8 AND Attribute value is =dd[7]
Attribute name is =output2 AND Attribute value is =ee[7]
Attribute name is =output4 AND Attribute value is =ff[511]
Attribute name   is  =output6 AND Attribute value  is =gg[15]
Attribute name   is  =output7 AND Attribute value  is =hh[1]
