Google Analytics正则表达式包含并排除了没有负面预测的字符串

问题描述

我试图在Google Analytics中使用正则表达式设置目标，以匹配应包含字符串_thanks但不应包含-cl-或-wf-或 - 的网址的网址。 WL-。

如果Google Analytics支持负面预测，这样做会更容易，但不幸的是它不会。

例如，目标应该匹配：

  /ba-ck-wp-example-of-a-page_thanks.html?ad = 1073 
 /ba-default-page_thanks.html 
 /ba-nt-visit-some-page_thanks.html?ad=1731 
  

但不应该匹配：

  / ba-cl-a- free-quote_thanks.html 
 /ba-wf-information-report_thanks.html 
 /ba-wl-information-otherreport-example_thanks.html 
  

任何帮助都将不胜感激。

解决方案

  ^（：[^  - ] |  - （？：？？[^ CW] | C [^ 1] | W [^ a]并） -  |  -  {2} [^  - ]）* _thanks 
  

正如您所看到的，复杂性随着您不想要的单词的长度而增加匹配（在这种情况下，4个字符）增长。

I'm trying to set up a Goal in Google Analytics using regular expressions to match urls that should contain the string "_thanks" but should not match urls that contain "-cl-" or "-wf-" or "-wl-".

This would be easier to do if Google Analytics would support negative lookahead, but unfortunately it doesn't.

For example the Goal should match:

/ba-ck-wp-example-of-a-page_thanks.html?ad=1073
/ba-default-page_thanks.html
/ba-nt-visit-some-page_thanks.html?ad=1731

But shouldn't match:

/ba-cl-a-free-quote_thanks.html
/ba-wf-information-report_thanks.html
/ba-wl-information-otherreport-example_thanks.html

Any help would be much appreciated.

解决方案

^(?:[^-]|-(?:[^cw].?|c[^l]|w[^fl])-|-.{2}[^-])*_thanks

As you can see, the complexity increases as the length of the words you don't want to match (in this case 4 characters) grows.
