查找字符串Ruby中的所有单词“The”

Question

我有这样的绳子

the horse and the hound and the horn that belonged to

如何在字符串中的“the”字之后得到所有单词？所以它就这样回来了

the horse, the hound, the horn

Answer 1

您可以使用String#scan获取每个"the“加一个空格，后面跟着任何单词，然后join这些结果：

"the horse and the hound and the horn that belonged to".scan(/\bthe \w+/).join(", ")
# "the horse, the hound, the horn"
