ruby - 正则表达式 - 分隔符之间的所有子字符串

Question

简单正则表达式的小问题...我有一个输入，需要两个单词之间的文本。输入示例:

Blah Blah 
Word1 
New line text I need 
Another important sentence for me 
Word2 
Blah blah 
Word1 
Line of important text 
Word2 
The end

我需要 Word1 和 Word2 之间的所有文本。有什么提示吗？

Answer 1

您可以使用正则表达式的先行和后行功能:

str = <<HERE
Blah Blah
Word1
New line text I need
Another important sentence for me
Word2
Blah blah
Word1
Line of important text
Word2
The end
HERE

str.scan(/(?<=Word1).+?(?=Word2)/m) # => ["\nNew line text I need\nAnother important sentence for me\n", "\nLine of important text\n"]
