설명

XmlDsigXPathTransform 클래스를 사용하면 XSLT 변환을 사용하여 XML 문서를 처리할 수 있습니다. 이 클래스는 XSLT를 사용하여 XML 노드를 서명하거나 암호화하려는 다른 XML 노드로 변환합니다.

클래스를 XmlDsigXsltTransform 사용하여 XSLT 변환을 사용하여 XML 문서의 특정 부분에 서명하거나 암호화합니다.

클래스를 설명하는 XmlDsigXsltTransform URI(Uniform Resource Identifier)는 필드에 의해 XmlDsigXsltTransformUrl 정의됩니다.

XSLT 변환에 대한 자세한 내용은 W3C XMLDSIG 사양의 섹션 6.6.5를 참조하세요.

생성자

XmlDsigXsltTransform()	XmlDsigXsltTransform 클래스의 새 인스턴스를 초기화합니다.
XmlDsigXsltTransform(Boolean)	지정된 경우 설명이 있는 XmlDsigXsltTransform 클래스의 새 인스턴스를 초기화합니다.

속성

Algorithm	현재 변환에서 수행되는 알고리즘을 식별하는 URI(Uniform Resource Identifier)를 가져오거나 설정합니다. (다음에서 상속됨 Transform)
Context	현재 XmlElement 개체가 실행되고 있는 문서 컨텍스트를 나타내는 Transform 개체를 가져오거나 설정합니다. (다음에서 상속됨 Transform)
InputTypes	현재 LoadInput(Object) 개체의 XmlDsigXsltTransform 메서드에 유효한 입력 형식의 배열을 가져옵니다.
OutputTypes	현재 GetOutput() 개체의 XmlDsigXsltTransform 메서드에서 가능한 출력 형식의 배열을 가져옵니다.
PropagatedNamespaces	서명으로 전파되는 네임스페이스가 포함된 Hashtable 개체를 가져오거나 설정합니다. (다음에서 상속됨 Transform)
Resolver	현재의 XmlResolver 개체를 설정합니다. (다음에서 상속됨 Transform)

메서드

Equals(Object)	지정된 개체가 현재 개체와 같은지 확인합니다. (다음에서 상속됨 Object)
GetDigestedOutput(HashAlgorithm)	파생 클래스에서 재정의된 경우 Transform 개체와 관련된 다이제스트를 반환합니다. (다음에서 상속됨 Transform)
GetHashCode()	기본 해시 함수로 작동합니다. (다음에서 상속됨 Object)
GetInnerXml()	XMLDSIG `<Transform>` 요소의 하위 요소로 포함하기에 적합한 XmlDsigXsltTransform 개체의 매개 변수에 대한 XML 표현을 반환합니다.
GetOutput()	현재 XmlDsigXsltTransform 개체의 출력을 반환합니다.
GetOutput(Type)	XmlDsigXsltTransform 형식의 현재 Stream 개체의 출력을 반환합니다.
GetType()	현재 인스턴스의 Type을 가져옵니다. (다음에서 상속됨 Object)
GetXml()	현재 Transform 개체의 XML 표현을 반환합니다. (다음에서 상속됨 Transform)
LoadInnerXml(XmlNodeList)	지정된 XmlNodeList 개체를 `<Transform>` 요소의 변환 관련 내용으로 구문 분석하여 현재 XmlDsigXsltTransform 개체의 내부 상태를 `<Transform>` 요소와 일치하도록 구성합니다.
LoadInput(Object)	지정된 입력을 현재 XmlDsigXsltTransform 개체로 로드합니다.
MemberwiseClone()	현재 Object의 단순 복사본을 만듭니다. (다음에서 상속됨 Object)
ToString()	현재 개체를 나타내는 문자열을 반환합니다. (다음에서 상속됨 Object)
