Using XPath

The System.Xml.XPath assembly is relatively small, containing only five classes, six enumerations, and one interface. There are two ways to select nodes from an XML document with XPath. The first, which was introduced in Chapter 5, uses the SelectNodes( ) and SelectSingleNode( ) methods of XmlNode. The second way uses the XPathNavigator class, obtained by calling XmlNode.GetNavigator( ) or XPathDocument.GetNavigator( ).

In this section, I’ll discuss these methods of using XPath in .NET.
