The XPathnavigator class is a subclass in the XPathDocumNet. DotNetfx V1, V2 has. XpathDocument has many new classes and methods in V2, more powerful, and xQuery, so you can get the same part and V1 version. static void Main (string [] args) {// xpath object load xml file XPathDocument xpDoc = new XPathDocument ( "booksort.xml"); // create a XPathNavigator object XPathNavigator xpNav = xpDoc.CreateNavigator (); // XPathExpression integrated XPath expression, if you need to sort / * xpaxpression xpexpr = xpnav.compile ("Descendant :: Book [Author / Last-name = 'Austen'); XPEXPR.Addsort (" Title ", XmlsortOrder.Descending, XmlcaseOrder.
