Hi I have a SOAP file.... i converted into string.
i would like to search the value of a perticular node.

The soap String is:

<soapenv:Envelope xmlns:soapenv="" xmlns:soapenc="" xmlns:xsd="" xmlns:xsi=""><soapenv:Body><GetQuoteRequest xmlns=""><symbol xmlns="">wqw</symbol><company xmlns="">qwq</company></GetQuoteRequest></soapenv:Body></soapenv:Envelope>

the program to look for perticular node is
public XPathNavigator(String xmlSource) throws TransformerException{
if ( xmlSource!=null) {
Debug.println("XPath xml=" + xmlSource);
String xpath = "/Envelope/Body/GetQuoteRequest/symbol";
InputSource inputSource = new InputSource(new ByteArrayInputStream(xmlSource.getBytes()));
DocumentBuilderFactory dfactory = DocumentBuilderFactory.newInstance();
try {
root = dfactory.newDocumentBuilder().parse(inputSource);
NodeIterator nodeIterator = XPathAPI.selectNodeIterator(root, xpath);
Node node = nodeIterator.nextNode();
System.out.println("the node u r searching is : " + node.getNodeName());
System.out.println("value of the node : " + node.getNodeValue());

catch (ParserConfigurationException pce) {
throw new TransformerException(pce.getMessage());
catch (IOException ioe) {
throw new TransformerException(ioe.getMessage());
catch (SAXException se){
throw new TransformerException(se.getMessage());


I am getting the node.But the value of the node am getting is null

PLZ help me ....

If you check the table of the API documentation org.w3c.dom Interface Node you will find that for an Element getNodeValue() will always return null. So either use the Node's getTextContent() method instead or append "/child::text()" to your XPath expression.
