Extract Node Values using XPATH

Question

This may be a repeat question.
No offence meant
I am using XPATH to extract values from the nodes.
I need to extract the value of i:RequestedBy Node using XPATH
<?xml version="1.0" encoding="UTF-8"?>
<i:Interest>
<i:Status>0</i:Status>
<i:Generation>2</i:Generation>
<i:Details xsi:type="i:vanilla.details.stock">
   <i:RequestedBy>AA.MM</i:RequestedBy>
The above XML is of type Document
Document msgDoc;
XPath xpath = XPathFactory.newInstance().newXPath();
XPathExpression expr;
Object result=null;
     try {
              expr = xpath.compile("i:Interest/i:Details/i:RequestedBy/text()");
              result = expr.evaluate(msgDoc, XPathConstants.NODESET);
           NodeList nodes = (NodeList) result;
            for (int i = 0; i < nodes.getLength(); i++) {
             System.out.println(nodes.item(i).getNodeValue());
     } catch (XPathExpressionException e1) {
     e1.printStackTrace();
                         I am getting null/
Is my XPATH correct?

I don't know if your XPath is correct or not. Your XML is not well-formed because the namespace declarations are missing. And I don't see where you set the namespace context for your XPath object; that is quite likely why it doesn't do what you want.
