如何匹配可在任何地方发生换行的正则表达式？

例如，如果我想要匹配“数以千计的海龟蛋”，它应该符合以下所有情况。（甚至是换行符在单词内的情况。）

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/

或此版本确保数千和鸡蛋不属于另一个词（如 ... eggsbath ）

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

Answer 2

您可以使用标记“s”来匹配所有换行符。

如果您使用正则表达式“/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，换行符被视为空格。所以只要你使用\ s来匹配单词之间的差距。例如：

#thousands \ SOF \ sturtle \ seggs＃SI

正则表达式与换行符匹配
