使用在文件中多次出现的标记来分割线条

我有一个文件，其内容如下：

this is test line 1 this is testing purpose  am inside of public doing lot of stuffs and priting result here   am inside of another public doing another set of stuffs and priting here  

我想将此文件拆分为三个不同的部分：

1. 不属于任何部分的线条
2. 第一部分内部的线条
3. 第二部分内部的线条

我尝试了take_while和drop_while ，

 File.open(filename).each_line.take_while do |l| !l.include?('') end.drop_while do |l| !l.include?('') end.drop(1)) 

但它只提取第一个 … 部分。

我正在寻找更好的解决方案。 任何建议将不胜感激。

 File.read(filename).split(/<\/?public>/) .map(&:strip) .reject(&:empty?) # [0..2] if the file has a tail #⇒ [ # [0] "this is test line 1 \nthis is testing purpose", # [1] "am inside of public\ndoing lot of stuffs and priting result here", # [2] "am inside of another public\ndoing another set of stuffs and priting here" # ]
