我正在嘗試為具有起始引號(hào)但沒(méi)有結(jié)束引號(hào)的子字符串構(gòu)建正則表達(dá)式。下面是一個(gè)示例字符串"The fish was 2 long. I said: Give me that fish!.The fish was 2" long. I said: Give me that fish!."The fish was 2 long. I said: Give me that fish!."The fish "was 2 long". I said: "Give me that fish!.所以表達(dá)式的有效輸出是String 1 - The fish was 2 long. I said: Give me that fish!String 2 -  long. I said: Give me that fish!.String 3 - No outputString 4 - Give me that fish!.任何想法如何構(gòu)建正則表達(dá)式。
