The XmlValidatingReader class is obsolete in .NET Framework 2.0.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 Validating XML Data with XmlReader. |
The following example reads an XML file and displays each node.
using System; using System.IO; using System.Xml; public class Sample { private const String filename = "items.xml"; public static void Main() { XmlTextReader txtreader = null; XmlValidatingReader reader = null; try { //Load the reader with the data file and ignore all white space nodes. txtreader = new XmlTextReader(filename); txtreader.WhitespaceHandling = WhitespaceHandling.None; //Implement the validating reader over the text reader. reader = new XmlValidatingReader(txtreader); reader.ValidationType = ValidationType.None; //Parse the file and display each of the nodes. while (reader.Read()) { switch (reader.NodeType) { case XmlNodeType.Element: Console.Write("<{0}>", reader.Name); break; case XmlNodeType.Text: Console.Write(reader.Value); break; case XmlNodeType.CDATA: Console.Write("<![CDATA[{0}]]>", reader.Value); break; case XmlNodeType.ProcessingInstruction: Console.Write("<?{0} {1}?>", reader.Name, reader.Value); break; case XmlNodeType.Comment: Console.Write("<!--{0}-->", reader.Value); break; case XmlNodeType.XmlDeclaration: Console.Write("<?xml version='1.0'?>"); break; case XmlNodeType.Document: break; case XmlNodeType.DocumentType: Console.Write("<!DOCTYPE {0} [{1}]", reader.Name, reader.Value); break; case XmlNodeType.EntityReference: Console.Write(reader.Name); break; case XmlNodeType.EndElement: Console.Write("</{0}>", reader.Name); break; } } } finally { if (reader!=null) reader.Close(); } } } // End class
The example uses the file, items.xml, as input.
<?xml version="1.0"?> <!-- This is a sample XML document --> <!DOCTYPE Items [<!ENTITY number "123">]> <Items> <Item>Test with an entity: &number;</Item> <Item>test with a child element <more/> stuff</Item> <Item>test with a CDATA section <![CDATA[<456>]]> def</Item> <Item>Test with a char entity: A</Item> <!-- Fourteen chars in this element.--> <Item>1234567890ABCD</Item> </Items>
