Problem in reading XML contents

Question

Hi all,
I have a problem in extracting a portion of the XML file.
the XML is
<x>
     <y1></y1>
     <y2>
          <value1>One</value1>
          <value2>Two</value2>
          <value3>Three</value3>     </y2>
     <y3></y3>
</x>the code i have written is
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
public class DOMParserDemo
    public static void main(String s[]){
        try{
            DocumentBuilder docBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
            Document document = docBuilder.parse("doc.xml");
            NodeList nodeList = document.getElementsByTagName("y2");
            Node node = nodeList.item(0);
            NodeList nList = node.getChildNodes();
            int len = nList.getLength();
            for(int i=0; i<len; i++){
                System.out.println(nList.item(i).getNodeName());
        }catch(Exception e){
            e.printStackTrace();
} I got the result as.
#text
value1
#text
value2
#text
value3
#text
where i expect the value to be prinited in the place of #text
can any one please help me to display the content correctly.
thanks in advance

This gets the element's contents - using concat from the other thread - you just need to navigate down the tree to the right depth:      NodeList nodeList = document.getElementsByTagName("y2");
      // for every y2 element
      for (int index1 = 0, length1 = nodeList.getLength(); index1 < length1; index1++) {
        final Element y2 = (Element)nodeList.item(index1);
        final NodeList y2Children = y2.getChildNodes();
        // for every child of a y2 element
        for (int index2 = 0, length2 = y2Children.getLength(); index2 < length2; index2++) {
          final Node child = y2Children.item(index2);
          // if that child node is an element node
          if (child.getNodeType() == Node.ELEMENT_NODE) {
            Element element = (Element)child;
            // print it's name, and the concatenation of any text nodes nested in it
            System.out.println(concat(element.getChildNodes(),
                                      new StringBuffer(element.getNodeName()).append(" = ")));
