XMLFileParsing Using DOM In Blackberry

The sample XML file is:

sample.xml:

<ROOT>
<ROW Name="Product Name~B" CheckBox="" Type="PerformanceNormal" Count="1" ChildCount="1" Show="Y" Refine="B">   
   <COL Page="1" Image="" ProductID="3">Sainsbury's aromatherapy citrus mint</COL>
   <COL Page="1" Image="" ProductID="4">TestPerf</COL>      
   <COL Page="2" Image="" ProductID="25">Acb</COL>
</ROW>
<ROW Name="Region~H" CheckBox="" Type="PerformanceNormal" Count="2" ChildCount="1" Show="Y" Refine="H">   
   <COL Page="1" Image="" ProductID="3">Western Europe</COL>  
   <COL Page="1" Image="" ProductID="5">Western Europe</COL>
   <COL Page="1" Image="" ProductID="24">Central and Eastern Europe</COL>   
</ROW>

</ROOT>
--------------------------------
and parse this xml file like:

XMLFileParsingScreen.java :

public class XMLFileParsingScreen extends MainScreen implements FieldChangeListener
{
    private ButtonField domparser;
    public XMLFileParsingScreen() {
        createGUI();
    }
    private void createGUI(){
        domparser=new ButtonField("DOM Parser");
        domparser.setChangeListener(this);
        add(domparser);       
    }
    public void fieldChanged(Field field, int context)
    {
        if(field==domparser)
        {
            ReadAndPrintXMLfileUsingDOM();
        }      
    }
    public void ReadAndPrintXMLfileUsingDOM()
    {

        try {
              DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
              DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
              InputStream rStream = null;
                  try
                  {
                      rStream = getClass().getResourceAsStream("sample.xml");
                  }catch (Exception e)
                  {
                      System.out.println(e.getMessage());
                  }
                  Document doc = docBuilder.parse(rStream);
                  doc.getDocumentElement ().normalize ();
                  System.out.println ("Root element of the doc is " +

                NodeList listOfPersons = doc.getElementsByTagName("ROW");
                int totalPersons = listOfPersons.getLength();
                System.out.println("Total no of people : " + totalPersons);
                for(int s=0; s<listOfPersons.getLength() ; s++)
                {
                    Node firstPersonNode = listOfPersons.item(s);
                    Element firstPersonElement = (Element)firstPersonNode;

                    NodeList firstNameList = firstPersonElement.getElementsByTagName("COL");

                    for(int j=0;j<child_lng;j++)
                    {
                            Node innernode=firstNameList.item(j);

//                             NamedNodeMap attributes = innernode.getAttributes();
                               Node value=firstNameList.item(j).getChildNodes().item(0);
                             System.out.println( "==============Page value = " + firstPersonElement1.getAttribute( "Page" ) );
                             System.out.println( "==============Image value = " + firstPersonElement1.getAttribute( "Image" ) );
                             System.out.println( "==============ProductID value = " + firstPersonElement1.getAttribute( "ProductID" ) );
                             System.out.println("+++++++++++++++Node Value : " +value.getNodeValue());
                          
                    }
                 }
          }catch (SAXParseException err)
          {
              System.out.println ("** Parsing error" + ", line "
