Poznámky

Poznámka

Počínaje rozhraním .NET Framework 2.0 doporučujeme vytvářet XmlWriter instance pomocí XmlWriter.Create metody a XmlWriterSettings třídy , abyste mohli využívat nové funkce.

Odsazení se provádí na následujících typech uzlů: DocumentType, Element, Comment, ProcessingInstructiona CDATASection. Na všechny ostatní typy uzlů to nemá vliv. Interní XmlTextWriter podmnožinu DTD neodsadí. Můžete ale použít formátování interní podmnožinu DTD následujícím postupem.

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);
