請(qǐng)大家?guī)兔�，先謝了！
我想實(shí)現(xiàn)這樣的功能：  在文本中有很多段如，以Starting行開頭， exit行開頭結(jié)尾的段，Starting 到exit中間的數(shù)據(jù)不一樣，還有其他不一樣開頭的數(shù)據(jù)。

比如文本內(nèi)容：

Starting (AXX BXX CXXX DXX EXX FXX HXX GXX IXX)
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.
2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.

2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.

exit status=0

License Option: ident

Starting (AXX BXX CXXX DXX EXX FXX HXX GXX IXX)

2017/03/02 17:37:16 ** Error: Unable to determine server for project 'test'.


exit status=0

The message returned from the system is: libgd_sh.so: cannot open shared object file: No such file or directory

exit status=0

怎么用正則表示式實(shí)現(xiàn)： 把Starting 到 exit所有段的內(nèi)容抓出來？

多謝！達(dá)到目的了，能否解釋下f=1 f=0是什么功能？
非常感謝！

一個(gè)用于標(biāo)識(shí)的變量 在區(qū)間開始(Starting)的時(shí)候開啟 在區(qū)間結(jié)束(exit)的時(shí)候關(guān)閉
