public override bool MoveToAttribute(
	string name
)

Return Value

Type: System.Boolean
true if the attribute is found; otherwise, false. If false, the position of the reader does not change.

NoteNote

The XmlValidatingReader class is obsolete in .NET Framework 2.0. You can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. For more information, see the Remarks section of the XmlReader reference page.

After calling this method, the Name, NamespaceURI, and Prefix properties reflect the properties of that attribute.

The following example reads an attribute with text and entity reference nodes.

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

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

    try
    {
       //Create the XML fragment to be parsed. 
       string xmlFrag ="<book genre='novel' misc='sale-item &h; 1987'></book>";

       //Create the XmlParserContext.
       XmlParserContext context;
       string subset = "<!ENTITY h 'hardcover'>";
       context = new XmlParserContext(null, null, "book", null, null, subset, "", "", XmlSpace.None);

       //Create the reader and set it to not expand general entities. 
       reader = new XmlValidatingReader(xmlFrag, XmlNodeType.Element, context);
       reader.ValidationType = ValidationType.None;
       reader.EntityHandling = EntityHandling.ExpandCharEntities;

       //Read the misc attribute. Because EntityHandling is set to 
       //ExpandCharEntities, the attribute is parsed into multiple text 
       //and entity reference nodes.
       reader.MoveToContent();
       reader.MoveToAttribute("misc");
       while (reader.ReadAttributeValue()){
          if (reader.NodeType==XmlNodeType.EntityReference)
            //To expand the entity, call ResolveEntity.
            Console.WriteLine("{0} {1}", reader.NodeType, reader.Name);
          else
             Console.WriteLine("{0} {1}", reader.NodeType, reader.Value);
        } 
     } 
     finally 
     {
        if (reader != null)
          reader.Close();
      }
  }
} // End class
