2 个解决方案

#1

You can use look-ahead and look-behind features of regular expressions:

您可以使用正则表达式的前瞻和后视功能:

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"]

#2

Assuming the text is fed as keyboard input

假设文本作为键盘输入

while gets()
   @found=true if line =~ /Word1/
   next unless @found
   puts line
   @found=false if line =~ /Word2/
end

will print all lines between Word1 and Word2 inclusive.

将打印Word1和Word2之间的所有行。
