NoteNote

The XmlValidatingReader class is obsolete in Microsoft .NET Framework version 2.0. You can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. For more information, see Validating XML Data with XmlReader.

The following example reads all the elements on the root node.

using System;
using System.IO;
using System.Xml;

public class Sample 
{
  public static void Main()
  {
    XmlValidatingReader reader = null;

    try
    {
       //Create the string to parse.
       string xmlFrag="<book genre='novel' ISBN='1-861003-78' pubdate='1987'></book> ";

       //Create the XmlNamespaceManager.
       NameTable nt = new NameTable();
       XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt);

       //Create the XmlParserContext.
       XmlParserContext context = new XmlParserContext(null, nsmgr, null, XmlSpace.None);

       //Create the XmlValidatingReader .
       reader = new XmlValidatingReader(xmlFrag, XmlNodeType.Element, context);
  
       //Read the attributes on the root element.
       reader.MoveToContent();
       if (reader.HasAttributes){
         for (int i=0; i<reader.AttributeCount; i++){
            reader.MoveToAttribute(i);
            Console.WriteLine("{0} = {1}", reader.Name, reader.Value);
         }
         //Move the reader back to the node that owns the attribute.
         reader.MoveToElement();
       }

     } 

     finally 
     {
        if (reader != null)
          reader.Close();
      }
