在字符串Ruby中查找单词“The”之后的所有单词
我有这样的字符串
the horse and the hound and the horn that belonged to
如何获取字符串中“the”字后的所有字词？所以它像这样返回
the horse, the hound, the horn
回答
您可以使用String#scan来获取每个“the”加上一个空格，后跟任何单词，然后join是这些结果：
"the horse and the hound and the horn that belonged to".scan(/bthe w+/).join(", ")
# "the horse, the hound, the horn"
- Don't forget to put a `b` before `the` in the regexp. `"breathe strongly and keep the pace"`
