Python 正则表达式搜索查找

我已经为我编写的脚本生成了一个日志文件，我想查找错误

日志文件如下所示：

24/05/2017 07:39:55 PM | DEBUG | Reading config file "FRGD-1_1.cfg". | main.py:81 - set_configparser()
...
...
24/05/2017 07:39:55 PM | DEBUG | Reading config file "FRGD-1_10.cfg". | main.py:81 - set_configparser()    
...
...
24/05/2017 08:39:55 PM | DEBUG | Reading config file "RFGD-1_5.cfg". | main.py:81 - set_configparser()    
...    
25/05/2017 09:53:47 PM | ERROR | KeyError. There is an issue with the config file for this download. Please check the config file for errors. | script.py:137 - main()    
...
... 
24/05/2017 10:39:55 PM | DEBUG | Reading config file "DPGD-4_15.cfg". | main.py:81 - set_configparser()  
...
...
24/05/2017 11:39:55 PM | DEBUG | Reading config file "ZXTD-3_1.cfg". | main.py:81 - set_configparser()
...  
25/05/2017 03:53:47 AM | ERROR | KeyError. There is an issue with the config file for this download. Please check the config file for errors. | script.py:137 - main()

24/05/2017 07:39:55 PM | DEBUG | Reading config file "FRGD-1_1.cfg". | main.py:81 - set_configparser()
...
...  
24/05/2017 07:39:55 PM | DEBUG | Reading config file "FRGD-1_10.cfg". | main.py:81 - set_configparser()

我想捕获引发错误的配置文件的所有名称

为了确定行，我查找具有以下内容的行：

DD/MM/YYYY HH:MM:SS PM | DEBUG | Reading config file "<file_name>.cfg".

在上面的示例中，它们是“RFGD-1_5.cfg”和“ZXTD-3_1.cfg”

我使用Python来运行这个正则表达式，因此我将整个文件连接到一行，并使用以下正则表达式

'(?<=Reading config file "(.{13})").+?\| ERROR \|'.

配置文件

import regex as re
rx = re.compile(r'''
                (?<=config\ file\ "([^"]+)"(?s:.*?))
                \|\ ERROR\ \|
                ''', re.VERBOSE)

print(rx.findall(string))
# ['RFGD-1_5.cfg', 'ZXTD-3_1.cfg']

将regex作为re导入
rx=重新编译（r''
（？嗨，简。谢谢你的时间。这就像魔术一样有效。我可以请你澄清一下你在这一部分做什么：（？s:.*）@jerry_doe:是的，请看修改后的答案。非常感谢你，简。这太棒了。我非常感谢。
