Multiple NameSpace in Xml Xpath value

[Karashimu]

Am new in using Xpath parsing in Java for Xmls. But I learnt it and it worked pretty well until this below issue am not sure how to go traverse to next node in this . Please find the below code and Let me know what needs to be corrected .\[code\] package test;import javax.xml.parsers.DocumentBuilder;import javax.xml.parsers.DocumentBuilderFactory;import javax.xml.transform.TransformerException;import javax.xml.xpath.XPath;import javax.xml.xpath.XPathConstants;import javax.xml.xpath.XPathExpressionException;import javax.xml.xpath.XPathFactory;import org.w3c.dom.Document;import org.w3c.dom.NodeList;public class CallTestcall { public static void main(String[] args) throws Exception { DocumentBuilderFactory domFactory = DocumentBuilderFactory .newInstance(); domFactory.setNamespaceAware(true); DocumentBuilder builder = domFactory.newDocumentBuilder(); String responsePath1 = "C:/Verizon/webserviceTestTool/generatedResponse/example.xml"; Document doc1 = builder.parse(responsePath1); String responsePath0 = "C:/Verizon/webserviceTestTool/generatedResponse/response.xml"; Document doc0 = builder.parse(responsePath0); example0(doc0); example1(doc1); } private static void example0(Document example) throws XPathExpressionException, TransformerException { System.out .println("\n*** First example - namespacelookup hardcoded ***"); XPath xPath = XPathFactory.newInstance().newXPath(); xPath.setNamespaceContext(new HardcodedNamespaceResolver()); String result = xPath.evaluate("s:Envelope/s:Body/ns1:UpdateSessionResponse", example); // I tried all the Values to traverse further to UpdateSessionResult but am not able to I used the following xpath expressions result = xPath.evaluate("s:Envelope/s:Body/ns1:UpdateSessionResponse/a:UpdateSessionResult", example); result = xPath.evaluate("s:Envelope/s:Body/ns1:UpdateSessionResponse/i:UpdateSessionResult", example); System.out.println("example0 : "+result); } private static void example1(Document example) throws XPathExpressionException, TransformerException { System.out .println("\n*** First example - namespacelookup hardcoded ***"); XPath xPath = XPathFactory.newInstance().newXPath(); xPath.setNamespaceContext(new HardcodedNamespaceResolver()); String result = xPath.evaluate("books:booklist/technical:book/:author", example); System.out.println("example1 : "+result); }}\[/code\]Please find the class that implements nameSpaceContext where I have added the prefixes\[code\]package test;\[/code\]import java.util.Iterator;import javax.xml.XMLConstants;import javax.xml.namespace.NamespaceContext;public class HardcodedNamespaceResolver implements NamespaceContext {\[code\]/** * This method returns the uri for all prefixes needed.
