具有负前瞻性的Regex，跨多行

Question

我有麻烦获得适当的正则表达式为我当前的任务。我需要所有CURDEPTH(0)值，不需要SYSTEM。

我尝试这个演示:

(?:(?!SYSTEM)[sS])*?CURDEPTH(d+)

的例子:

Answer 1

如果支持向后看断言中的量词，则可以检查前一行不包含SYSTEM.，然后匹配CURDEPTH(digits)

(?<!^.*bSYSTEM..*n.*)CURDEPTH(d+)

另一个选项是使模式更具体，并使用捕获组。

您可以从一个特定的模式开始匹配，然后匹配所有不以特定匹配和您想要匹配的内容开头的行。

在模式的末尾，捕获匹配中应该包含的内容。

^AMQd.*(?:n(?!AMQd|.*?bSYSTEM.).*)*ns*(CURDEPTH(d+))
