Examples

The following example reads an XML file and displays each of the nodes.

XmlReaderSettings settings = new XmlReaderSettings();
settings.DtdProcessing = DtdProcessing.Parse;
XmlReader reader = XmlReader.Create("items.xml", settings);

reader.MoveToContent();
 // 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;
 }
}
