注意

.NET Framework 2.0 以降では、 メソッドと クラスをXmlWriter.Create使用してインスタンスを作成XmlWriterしXmlWriterSettings、新しい機能を利用することをお勧めします。

インデントは、、および のDocumentTypeProcessingInstructionElementComment各ノードの種類に対してCDATASection実行されます。 他のすべてのノード タイプは影響を受けません。 では XmlTextWriter 、内部 DTD サブセットはインデントされません。 ただし、内部 DTD サブセットに書式設定を適用するには、次の操作を行うことができます。

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);
