带换行符的正则表达式匹配

Question

如何匹配可以在任何地方换行的正则表达式？

例如，如果我尝试匹配“数千个海龟蛋”，它应该匹配以下所有情况。(甚至在单词内部有换行符的情况下也是如此。)

Scientists have revealed that a mammoth effort to move *thousands of turtle eggs* from beaches around the Gulf of Mexico after the Deepwater Horizon oil spill may have saved almost 15,000 of the reptiles.

Answer 1

  /thousands\s+of\s+turtle\s+eggs/

或者这个版本，以确保数千和鸡蛋不是另一个单词的一部分(如...eggsbath)

  /\bthousands\s+of\s+turtle\s+eggs\b/

Answer 2

您可以使用标志"s“来匹配所有换行符。

如果使用正则表达式"/reptiles..*?sc/gis“，它将匹配"reptiles.sc”

Answer 3

使用“%s”开关。然后^$成为整个字符串的开始和结束，换行符被认为是空格。所以只要你使用\s来匹配单词之间的间隙。例如：

#thousands\sof\sturtle\seggs#si
