Question

좋아, 정규식이 많이 있지만 언제나처럼 그 중 아무 것도 내가하려는 작업과 일치하지 않는 것 같습니다. 여러 줄 정규식,

그래서를, 기본적으로, 나는 [HD]0501로 시작하는 모든 것을 가져옵니다.

나는 이것이 일치하는 것이 더 적합하다고 생각하지만, Regex 패턴 문자열과 정규 표현식 문자열 만 허용하는 미리 빌드 된 엔진을 살펴볼 것입니다.

원하는 결과를 얻기 위해 패턴 및 바꾸기 문자열을 제공하려면 어떻게해야합니까? Multiline Regex는 하드 코딩 된 구성입니까?

나는 원래 이런 일이 일 것이라고 생각 :

검색 : (?<Match>^[HD]0501\d+$),하지만 아무것도 일치하지 않습니다.

검색 : (?!^[HD]0501\d+$), 그러나 이것은 빈 문자열의 무리를 일치, 그리고 내가 대체 문자열을 넣어 알아낼 수 없었다.

은 검색 : (?!(?<Omit>^[HD]0501\d+$)), "그룹 '생략은'을 (를) 찾을 수 없습니다."

이것은 간단해야하지만, 언제나처럼, Regex는 나를 바보로 느끼게합니다. 도움말 크게 감사하겠습니다.

Answer 1

다음 패턴과 일치하는 시도 :

(?m)^(?![HD]0501).+(\r?\n)? 

과 빈 문자열로 대체합니다.

빠른 설명 :

• (?m)
  • 는 멀티 라인 모드를 활성화,338을되도록은 새 줄의 시작과 일치합니다.
• ^
  • 일치하는 새로운 라인의 시작;
• (?![HD]0501)
  • 가 있는지 미리 봐 더"H0501" 또는 "D0501";
• .+
  • 일치 하나 줄 바꿈 - 문자 이외의 많은 문자;
• (\r?\n)?
  • 일치 옵션 줄 바꿈.
