abstract class

This class represents a compiled XPath expression. An XPathExpression is returned by the Compile( ) method of XPathNavigator from an XPath expression string. The AddSort( ) method allows you to specify the order of returned nodes from the expression. SetContext( ) sets the namespace to use in the evaluation of the expression.
