包含一个词但不包含另一个词的字符串的正则表达式 [英] Regular expression for a string containing one word but not another

问题描述

我正在 Google Analytics 中设置一些目标，可以使用一些正则表达式帮助.

I'm setting up some goals in Google Analytics and could use a little regex help.

假设我有 4 个网址

http://www.anydotcom.com/test/search.cfm?metric=blah&selector=size&value=1
http://www.anydotcom.com/test/search.cfm?metric=blah2&selector=style&value=1
http://www.anydotcom.com/test/search.cfm?metric=blah3&selector=size&value=1
http://www.anydotcom.com/test/details.cfm?metric=blah&selector=size&value=1

我想创建一个表达式来识别包含字符串 selector=size 但不包含 details.cfm

I want to create an expression that will identify any URL that contains the string selector=size but does NOT contain details.cfm

我知道要找到一个不包含另一个字符串的字符串，我可以使用这个表达式:

I know that to find a string that does NOT contain another string I can use this expression:

(^((?!details.cfm).)*$)

但是，我不确定如何添加 selector=size 部分.

But, I'm not sure how to add in the selector=size portion.

任何帮助将不胜感激！

推荐答案

应该这样做:

^(?!.*details.cfm).*selector=size.*$

^.*selector=size.*$ 应该够清楚了.第一位，(?!.*details.cfm) 是一个否定的前瞻:在匹配字符串之前，它检查字符串不包含details.cfm"(前面有任意数量的字符)它).

^.*selector=size.*$ should be clear enough. The first bit, (?!.*details.cfm) is a negative look-ahead: before matching the string it checks the string does not contain "details.cfm" (with any number of characters before it).
