拆分文本文件混合格式

Question

我有一个文件

"Lots of text"
"Lots more Text"

"Tons
of
Text, I really 
Can't emphasize that enough really

"

我需要将文本部分放入单个文件中。

1.txt = "Lots of text"
2.txt = "Lots more Text"
3.txt = "Tons
         of
         Text, I really
         Can't emphasize that enough really"

不知道从哪里开始。在DOS和Linux中尝试了一些脚本创意。不要介意用Java编写它。
