Name

XPathExpression — System.Xml.XPath (system.xml.dll) abstract class

Synopsis

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

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.
