正则表达式提取包含异常堆栈跟踪的多行
regex extract multiple lines containing exception stacktrace
从日志文件中提取带有异常 strack trace 的多行错误的正确正则表达式是什么。这是我的例子。

这是我的正则表达式：(Error;(?:.*\r?\n?)\s)
这个正则表达式只 select 我一行或错误。实际上我想要一个可以 select 我 3 错误的正则表达式（第一个错误是单行错误，后来的 2 个错误是多行错误）。
我的正则表达式没有在错误行末尾转义 CRLF 或换行符。
每条记录的尾随边界是 Debug;、Verbose;、Info; 或 Error;。
有什么建议吗？
您可以使用以下正则表达式
/^Error;.*(?:\r?\n(?!Error;|Verbose;|Info;|Debug;).*)*/gm
请根据您使用的语言调整符号。

^ - start of a line (mmodifier makes the^` 匹配一行的开头而不是整个字符串)Error; - 匹配文字子串 Error;.* - 匹配行的其余部分(?:\r?\n(?!Error;|Verbose;|Info;|Debug;).*)* - 0+ 个序列：
\r?\n(?!Error;|Verbose;|Info;|Debug;) - 换行符后面没有任何括号内的替代项.* - 整行。
