如何使用python正则表达式从回溯中提取错误细节？

我想从回溯中提取错误细节，这些回溯是使用从日志文件中提取的，有很多不同类型的回溯，如下所示：

Traceback (most recent call last):
  File "/usr/lib/python2.7/runpy.py", line 174, in _run_module_as_main
    "__main__", fname, loader, pkg_name)
  File "/usr/lib/python2.7/runpy.py", line 72, in _run_code
    exec code in run_globals
  File "/root/env/common/test/test/__main__.py", line 5, in <module>
    main()
  File "/root/env/common/test/test/cli/parser.py", line 55, in main
    run_script(args)
  File "/root/env/common/test/test/cli/runner.py", line 124, in run_script
    exec_script(args.script, scope=globals(), root=True)
  File "/root/workspace/group/test_regression_utils.py", line 123, in exec_script
    cli_exec_script(*args,**kwargs)
  File "/root/env/common/test/test/cli/runner.py", line 186, in exec_script
    exec(compile(code, scriptpath, 'exec')) in scope
  File "shiju_12.py", line 30, in <module>

  File "/root/moaworkspace/group/testscript/utils/shiju_public.py", line 37, in shiju_move

Exception: close failed!
EndOfStream
EndOfStream

  File "/root/env/common/mator/mator/mator.py", line 520, in start
    raise IOError("RPC server not started!")
IOError: RPC server not started

我尝试了

detail\u regex=r'Traceback.*\n（\s+.*\n）*（.*）\n*'

第二个回溯是正确的，但第一个回溯结果是

（“异常：关闭失败！”，“EndOfStream”）

有什么想法吗

如果我将您的模式更改为

Traceback.*\n（\s+.*\n）*（.*？）\n*

，它适用于给定的示例。不过，我不确定它是否能完全解决您的问题。

检查回溯对象可能是一个更好的主意（虽然我记不清它们的确切名称）。噢，回溯是从日志文件中获得的。链接指向此answer@SwiftsNamesake我已更新您可以使用前瞻来定义何时停止匹配。

("XXXX", "Exception: close failed!")
("XXXX","IOError: RPC server not started")
