Comentarios

Nota:

A partir de .NET Framework 2.0, se recomienda crear XmlWriter instancias mediante el XmlWriter.Create método y la XmlWriterSettings clase para aprovechar las nuevas funcionalidades.

La sangría se realiza en los siguientes tipos de nodo: DocumentType, Element, Comment, ProcessingInstructiony CDATASection. El resto de tipos de nodo no se ven afectados. XmlTextWriter no aplica sangría al subconjunto DTD interno. Sin embargo, puede hacer lo siguiente para aplicar formato al subconjunto de DTD interno.

String name = "Employees";
String pubid = null;
String sysid = null;
String subset =
@"
    <!ELEMENT Employees (Employee)+>
    <!ELEMENT Employee EMPTY>
    <!ATTLIST Employee firstname CDATA #REQUIRED>
    <!ENTITY Company 'Microsoft'>]>
";
XmlTextWriter tw = new XmlTextWriter(Console.Out);
tw.WriteDocType(name, pubid, sysid, subset);
