A XmlDsigXPathTransform classe permite que você resolva um documento XML usando uma transformação XSLT. Essa classe usa XSLT para transformar nós XML em outros nós XML que você deseja assinar ou criptografar.
Use a XmlDsigXsltTransform classe para assinar ou criptografar partes específicas de um documento XML usando uma transformação XSLT.
O URI (Uniform Resource Identifier) que descreve a XmlDsigXsltTransform classe é definido pelo XmlDsigXsltTransformUrl campo .
Para obter mais informações sobre a transformação XSLT, consulte Seção 6.6.5 da especificação XMLDSIG do W3C.
Xml |
Inicializa uma nova instância da classe XmlDsigXsltTransform. |
Xml |
Inicializa uma nova instância da classe XmlDsigXsltTransform com comentários, se especificado. |
Algorithm |
Obtém ou define o URI (Uniform Resource Identifier) que identifica o algoritmo executado pela transformação atual. (Herdado de Transform) |
Context |
Obtém ou define um objeto XmlElement que representa o contexto do documento em que o objeto Transform atual está em execução. (Herdado de Transform) |

Load |
Carrega a entrada especificada no objeto XmlDsigXsltTransform atual. |
Memberwise |
Cria uma cópia superficial do Object atual. (Herdado de Object) |
To |
Retorna uma cadeia de caracteres que representa o objeto atual. (Herdado de Object) |
