Question

需要有关正则表达式的帮助才能选择多行。从我到目前为止，它一直有效，直到我把最后一个正则表达式放入。一旦我这样做，它就跳过中间的正则表达式。为安全起见，已删除密码。

我的目标

选择以当前配置结尾处开始的所有行版本，＆＃34;或者！就在它之前＆＃34;
使用＆＃34; secret＆＃34;
使用＆＃34;密码＆＃34;

我的正则表达式

(?s)Current configuration (.*)NVRAM|secret 5 +(\S+)|password 7 +(\S+)

编辑：在|之前和之后占用了大约空格它似乎突出了我想要的东西。但它并没有做整行。

Answer 1

这应该有效。

<强> REGEXP：

((?:\bCurrent configuration)(?:.*\n?){6})$|((?:\bsecret)(?:.)+$)|((?:\bpassword\s)(?:.)+$)

<强> INPUT：
