找到与特定正则表达式匹配的字符串，然后从该列表中排除任何符合一个或多个条件的内容

i'm using astrogrep to search email

我正在使用astrogrep来搜索电子邮件

to make it very tolerant i'm using this regex: [a-z0-9_.-]+@[a-z0-9_.-]+

让我非常宽容我正在使用这个正则表达式:[a-z0-9 _.-] + @ [a-z0-9 _.-] +

but I have to ignore some email from that search

但我不得不忽略该搜索的一些电子邮件

if i find ABCD or YXZ at the begining of the email, like [e-mail] and YXZ [e-mail] I have to exclude it from the result

如果我在电子邮件开头找到ABCD或YXZ,如[e-mail]和YXZ [e-mail]我必须将其从结果中排除

I have tried a fews things like;

我尝试了一些类似的事情;

(?!abcd)|([a-z0-9_.-]+)@[a-z0-9_.-]+
^(?!abcd+)|([a-z0-9_.-]+)@[a-z0-9_.-]+
(?!abcd)([a-z0-9_.-]+)@[a-z0-9_.-]+
(?!abcd+)([a-z0-9_.-]+)@[a-z0-9_.-]+

etc...

this seem easy when i did my search on google but it seem i cannot find a way to make it work

当我在谷歌搜索时,这似乎很容易,但似乎我找不到让它工作的方法

2 个解决方案

#1

it seem that the answer was this \b(?!abcd|xyz)[a-z0-9_.-]+@[a-z0-9_.-]+

似乎答案是这个\ b(?!abcd | xyz)[a-z0-9 _.-] + @ [a-z0-9 _.-] +

#2

You can use negative lookahead like this:

您可以像这样使用负向前瞻:

(?!\b(abcd|xyz))[a-z0-9_.-]+@[a-z0-9_.-]+\b

This will fail the match if abcd or xyz is found at the start of input.

如果在输入开始时找到abcd或xyz,则匹配将失败。
