查找字符串 Ruby 中单词"The"后的所有单词

Question

我有这样的字符串

the horse and the hound and the horn that belonged to

如何获取字符串中单词后面的所有单词？所以它像这个一样返回

the horse, the hound, the horn

Answer 1

您可以使用String#scan来获取每个"；加上后面跟着任何单词的空白，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"
