DTD 연결을 통한 유효성 검사 강제 종료

Question

내 컴퓨터에없는 문서에서 DTD로 문서의 유효성을 검사하고 있으며 인터넷에 저장되어 있습니다.

나는 현재 다음과 같은 예외

System.Xml.XmlException: An error has occurred while opening external DTD 'http://xml.cxml.org/schemas/cXML/1.2.020/cXML.dtd': Unable to connect to the remote server --->

을 얻고 나는 그것을 찾아 수있는 파일에 액세스 할 알고있다. 하지만 .NET에서 액세스 할 수없는 이유는 무엇입니까?! 미리 감사드립니다.

[http://xml.cxml.org/schemas/cXML/1.2.020/cXML.dtd] dtd 파일을 탐색 할 때 예외가 발생합니다.

XML 구문 분석 오류 : 구문 오류 위치 : http://xml.cxml.org/schemas/cXML/1.2.020/cXML.dtd 라인 번호 15, 열 1 :

는 그냥 DTD 파일을 다운로드하고 로컬 DTD를 액세스 해보십시오. 문제의 범위를 좁힐 수 있습니다.
