正则表达式匹配一个没有跟在其他两个词之后的词 [英] Regex match a word not followed by two other words

问题描述

我有一些链接:

utmcsr=rdstation|utmccn=curso-intro-coaching|utmcmd=inbound|utmctr=link3
utmcsr=rdstation|utmccn=agenda-psc|utmcmd=email
utmcsr=rdstation|utmccn=pnl-porto-alegre

我想构建一个与 rdstation 匹配的正则表达式，后跟 inbound OR email.

I want to build a regex expression that matches the rdstation not followed by inbound OR email.

我试过 rdstation(?!(email|inbound)) 但没有用.

推荐答案

问题是你的负前瞻直接锚定在 rdstation 之后的位置.它只会排除这样的字符串:

The problem is that your negative lookahead is anchored to the position directly after rdstation. It would only exclude strings like this:

rdstationemail asdf 123 4

你需要确保它可以在 rdstation 之后的任何地方匹配:

You need to make sure it can match anywhere after rdstation:

rdstation(?!.*(email|inbound))

此处的工作示例.
