설명

이 클래스는 보안 시스템 내에서 사용하기 위한 간단한 XML 개체 모델의 간단한 구현이며 일반 XML 개체 모델로는 사용되지 않습니다. 이 설명서에서는 XML에 대한 기본 지식을 가정합니다.

요소에 대한 간단한 XML 개체 모델은 다음 부분으로 구성됩니다.

  • 태그는 요소 이름입니다.

  • 특성은 요소에서 0개 이상의 이름/값 특성 쌍입니다.

  • 자식은 및 </tag>내에 <tag> 중첩된 0개 이상의 요소입니다.

특성 기반 XML 표현을 사용하여 보안 요소와 해당 값을 표현하는 것이 좋습니다. 즉, 요소의 속성은 특성으로 표현되고 속성 값은 특성 값으로 표현됩니다. 태그 내에서 텍스트를 중첩하지 않습니다. 모든 <tag>text</tag> 표현의 경우 형식 <tag value="text"/> 의 표현을 일반적으로 사용할 수 있습니다. 이 특성 기반 XML 표현을 사용하면 가독성이 향상되고 결과 XML serialization의 WMI 이식성이 용이합니다.

특성 이름은 한 문자 이상이어야 하며 이 될 null수 없습니다. 요소 기반 값 표현을 사용하는 경우 양식에 <tag/> 표시되는 텍스트 문자열이 있는 null 요소가고, 그렇지 않으면 텍스트가 및 </tag> 토큰으로 <tag> 구분됩니다. 두 폼을 특성과 결합할 수 있습니다. 특성이 있는 경우 표시됩니다.

요소의 태그, 특성 및 텍스트(있는 경우)는 항상 대/소문자를 구분합니다. XML 양식에는 따옴표가 포함되어 있으며 필요한 경우 이스케이프됩니다. XML에 사용할 수 없는 문자를 포함하는 문자열 값은 을 반환합니다 ArgumentException. 이러한 규칙은 모든 속성 및 메서드에 적용됩니다.

참고

성능상의 이유로 문자 유효성은 요소가 XML 텍스트 형식으로 인코딩된 경우에만 검사되며 속성 또는 메서드의 모든 집합에서는 검사되지 않습니다. 정적 메서드는 필요한 경우 명시적 검사를 허용합니다.
