在Python中解析log4j [英] Parsing log4j in Python

问题描述

我有一个日志文件(log4j xml-ish格式)，我试图将信息提取出来并在我的Python模块中使用.我可以将此文件视为XML吗?我的直觉告诉我不...如果没有，解析数据的最佳方法是什么?以下是日志文件的一部分.该文件不包含您的标准doctype或版本标头，这就是为什么我说"xml-ish".

I have a log file (log4j xml-ish format) that I am trying to pull info out of and use in my Python module. Could I treat this file as if it were XML? My gut is telling me no... If not, what is the best way to parse the data? Below is a section of the log file. The file does not include your standard doctype or version headers which is why I said "xml-ish."

抱歉，代码混乱，我只是想让大家都对格式有所了解.无论如何，我目前正试图从QueueEntryID="d5fbbe98a1194e0da573b51a0c8040fb"中提取值，有什么建议吗?谢谢！

Sorry for the messy code, I just wanted to make you all can get an idea of the formatting. Anyway, I'm currently just trying to pull the value from QueueEntryID="d5fbbe98a1194e0da573b51a0c8040fb" Any suggestions? Thank you!

推荐答案

我想您可以使用诸如DOM或SAX之类的标准XML工具来对此进行解析.否则，请玩re或htmllib.

I would imagine that you could use standard XML tools like DOM or SAX to parse this. Otherwise, have fun with re or htmllib.
