注釈

このクラスは、セキュリティ システム内で使用するための単純な XML オブジェクト モデルの軽量実装であり、一般的な XML オブジェクト モデルとして使用されるものではありません。 このドキュメントでは、XML に関する基本的な知識を前提としています。

要素の単純な XML オブジェクト モデルは、次の部分で構成されます。

• タグは要素名です。

• 属性は、 要素の 0 個以上の名前と値の属性のペアです。

• 子は、 および </tag>内<tag>に入れ子になった 0 個以上の要素です。

属性ベースの XML 表現を使用して、セキュリティ要素とその値を表現することを強くお勧めします。 つまり、要素のプロパティは属性として表され、プロパティ値は属性値として表されます。 タグ内でテキストを入れ子にしないようにします。 任意 <tag>text</tag> の表現では、通常、型 <tag value="text"/> の表現を使用できます。 この属性ベースの XML 表現を使用すると、読みやすさが向上し、結果として得られる XML シリアル化の WMI 移植性が容易になります。

属性名は 1 文字以上である必要があり、 にすることはできません null。 要素ベースの値表現を使用する場合、テキスト文字列を含む要素はnullフォームで<tag/>表されます。それ以外の場合、テキストは および </tag> トークンで<tag>区切られます。 両方のフォームを属性と組み合わせることができます。属性が存在する場合は表示されます。

要素のタグ、属性、テキスト (存在する場合) は、常に大文字と小文字が区別されます。 XML フォームには、必要に応じて引用符とエスケープが含まれています。 XML で使用するために無効な文字を含む文字列値は、 ArgumentExceptionになります。 これらの規則は、すべてのプロパティとメソッドに適用されます。

注意

パフォーマンス上の理由から、文字の有効性は、要素が XML テキスト 形式にエンコードされている場合にのみチェックされ、プロパティまたはメソッドのすべてのセットではチェックされません。 静的メソッドを使用すると、必要に応じて明示的なチェックを行うことができます。
