I want to parse java log. I need to get only Error log with tracer.
For example:
2022-06-21 19:19:56,665 ERROR [scheduler-3] o.s.s.s.TaskUtils$LoggingErrorHandler - Unexpected error occurred in scheduled task
java.lang.NullPointerException: null
at ...
at ...
...
2022-06-21 19:19:56,666 DEBUG
I need take all until new log line with data. It is:
2022-06-21 19:19:56,665 ERROR [scheduler-3] o.s.s.s.TaskUtils$LoggingErrorHandler - Unexpected error occurred in scheduled task
java.lang.NullPointerException: null
at ...
at ...
...
What is the best way to make regular expression for this task with repeating symbols? In my way there are something like that .+\n\t If I not use repeat it seems ugly, like that REG_EXP_2 = r'\d{4}-\d{2}-\d{2}\s\d{2}:\d{2}:\d{2},\d{3}\sERROR.+\n.+\n\t.+\n\t.+' So I need to find all log strings with model .+\n\t until I will find new data line.
I triet to use model with repeating symbols, but it parses only last finding string.
Thank you.
To match ERROR amd all the following lines that do not start with a date:
^\d{4}-\d{2}-\d{2}\s\d{2}:\d{2}:\d{2},\d{3}\sERROR\b.*(?:\n(?!\d{4}-\d{2}-\d{2}\s).*)*
