Microsoft .NET Framework version 2.0 リリースでは、System.Xml.XmlWriter.Create メソッドと XmlWriterSettings クラスを使用して XmlWriter インスタンスを作成することをお勧めします。これにより、このリリースで導入されたすべての新機能を十分に活用できます。詳細については、「XML ライタの作成」を参照してください。 |
Microsoft Visual C# コードの例を次に示します。
writer.Formatting = Formatting.Indented; writer.WriteStartElement("root"); writer.WriteAttributeString("xmlns","x",null,"urn:abc"); writer.WriteStartElement("item"); writer.WriteStartAttribute("href",null); writer.WriteString("#"); writer.WriteQualifiedName("test","urn:abc"); writer.WriteEndAttribute(); writer.WriteEndElement(); writer.WriteEndElement(); writer.Close();
ns を現在の既定の名前空間に割り当てると、プリフィックスは生成されません。
属性値を書き込むときに、ns が見つからないと、このメソッドはプリフィックスを生成します。要素の内容を書き込むときに、ns が見つからないと、このメソッドは例外をスローします。
このライタが名前空間をサポートしている (Namespaces が true に設定されている) 場合、このメソッドは、その名前が W3C 勧告『Namespaces in XML』(http://www.w3.org/TR/REC-xml-names) に準拠した有効な名前かどうかも確認します。
