XPathExpression

Synopsis

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.
