Question

从日志文件中使用异常strack跟踪提取多行错误的正确正则表达式是什么。这是我的例子。

Verbose;MyComputer;07.02.2017 12:42:48,831;Area=;SubArea=;SessionId=;StepId;User=;Message=Repository CareProviderRepository:START GetCareProviderByZsrMethod with ZSR: H110702

以下是我的RegEx：(Error;(?:.*\r?\n?)\s)

这个正则表达式只选择我一行或错误。其实我想要一个正则表达式可以选择我3错误（第一个错误是单行，后来2错误是多行）。

我的正则表达式不是在错误行末尾转义CRLF或换行符。

每条记录的尾随边界为Debug;，Verbose;，Info;或Error;。

有任何建议吗？

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。

<强>详情

^ - start of a line ( m modifier makes the ^`匹配行的开头而不是整个字符串）
Error; - 匹配文字子字符串Error;
.* - 与该行的其余部分匹配
(?:\r?\n(?!Error;|Verbose;|Info;|Debug;).*)* - 0+序列：
- \r?\n(?!Error;|Verbose;|Info;|Debug;) - 括号内没有任何替代品的换行符
- .* - 整条线。

正则表达式提取包含异常堆栈跟踪的多行
