Subject: XPATH Issue

Hi

I have a very strange problem and I have spend a whole day trying to figure what

is wrong.


I have a XPATH expression, and if I evaluate from a XML File on disk it works.

If I evaluate from a DOM Object from a HTTP Source, it doesn't  work. Both the
documents are exactly same.

XML Document
SUCCESS</RetrieveResult></RetrieveResponse></s:Body></s:Envelope>

// Document from File

                 // Parse the XML as a W3C document.
                 DocumentBuilder builder =
                     DocumentBuilderFactory.newInstance().newDocumentBuilder();
                 Document document = builder.parse(new
File("C:\\Users\\smirxj0\\Documents\\Java\\GPN.xml"));

// Alternatively Document from HTTP

               InputStream isr = httpConn.getInputStream();
               Document document = builder.parse(isr);

// If I print this Document, I have the same output as the XML file


// XPATH Expression

                 XPath xpath = XPathFactory.newInstance().newXPath();
                 expression = "//RetrieveResponse/RetrieveResult/StatusType";
                 String statusString = (String)
                     xpath.evaluate(expression, document,
XPathConstants.STRING);

System.out.println("String is: " + statusString);

Please let me know where am I going wrong?

Is it a XPATH issue?
