Read the XML Using XPath FROM XML Text Reader

 

Copy the below code and call GetXmlNodeValue method to pass on XMLTextReader object and Xpath and get the result.

void GetXmlNodeValue(XmlTextReader reader,string xpathQuery)
        {
            System.Console.WriteLine(“TestOne”);
            XPathDocument xdoc = new XPathDocument(reader);
            XPathNavigator nav = xdoc.CreateNavigator();
            XPathNodeIterator nodeItor = nav.Select(xpathQuery);
             //”STUFF/TYPE1/CENSUS[@COUNTRY=’USA’ and @YEAR=’1930′]/PAGE”);
            nodeItor.MoveNext();
            TraverseSiblings(nodeItor);
            System.Console.WriteLine();
        }

         void TraverseSiblings(XPathNodeIterator nodeItor)
        {
            XPathNodeIterator igor = nodeItor.Clone();
            PrintNode(igor.Current);
            igor.Current.MoveToNext();
            bool more = false;
            do
            {
                PrintNode(igor.Current);
                more = igor.Current.MoveToNext();
            } while (more);
        }

         void PrintNode(XPathNavigator nav)
        {
            System.Console.WriteLine(nav.Name + “:” + nav.Value +
                ” Type : ” + nav.NodeType.ToString());
        }
