XPathExpression

Synopsis

This class represents a compiled XPath expression. An XPathExpression is returned by the XPathNavigator.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.

public abstract class XPathExpression {
// Public Instance Properties
   public abstract field string Expression{get; } 
   public abstract field XPathResultType ReturnType{get; } 
// Public Instance Methods
   public abstract method void AddSort(object expr, 
        System.Collections.IComparer comparer);  
   public abstract method void AddSort(object expr, 
        XmlSortOrder order, XmlCaseOrder caseOrder, 
        string lang, XmlDataType dataType);  
   public abstract method XPathExpression Clone();  
   public abstract method void SetContext(
