正则表达式替代谷歌分析的负前瞻匹配

问题描述

我正在 Google Analytics(分析)上设置一些转化渠道.一种是分析从主站点到在虚拟目录上运行的辅助促销站点的流量(尽管在同一域中)

我应该补充一点，这是 Google Analytics 中的设置表单，我不能使用其他代码(PHP、JS、C# 等)，必须一步完成

例如:

• /default.aspx 或 /directory/default.aspx 或 /somedirname/default.aspx
• [到>]
• /promotion/default.aspx

在正则表达式领域，这将是:

• ^/(?!promotion)(.*).aspx
• [到>]
• ^/promotion/(.*).aspx

问题是 Google Analytics 不再支持否定前瞻，因此正则表达式 ^/(?!promotion)(.*).aspx 失败.(参考这里，第一次回复)>

还有其他方法可以做到这一点吗?

非常感谢.

解决方案

您可以采取两步走的方法(但我不知道在 Analytics 中是否可行):

1. 无条件替换:
   /(.*.aspx) -->/promotion/$1
2. 再次更换:
   /promotion/promotion/(.*) -->/promotion/$1

如果一切都失败了:

^/(?:[^p]|p[^r]|pr[^o]|pro[^m]|prom[^o]|promo[^t]|promot[^i]|promoti[^o]]|促销[^n])/(.*).aspx

I'm setting up some conversion funnels on Google Analytics. One is to analyse traffic going from the main site to a secondary promotional site running on a virtual directory (on the same domain though)

I should add, this is a setup form in Google Analytics, I can't using another other code (PHP, JS, C# etc) and it has to be done in one step

So for example something like:

• /default.aspx or /directory/default.aspx or /somedirname/default.aspx
• [to >]
• /promotion/default.aspx

In regular expression land, this would be:

• ^/(?!promotion)(.*).aspx
• [to >]
• ^/promotion/(.*).aspx

The problem is Google Analytics no longer supports negative lookaheads, so the regexp ^/(?!promotion)(.*).aspx fails. (Reference here, first reply)

Is there another way I can do this?

Many thanks.

解决方案

You could do a two-step approach (whether that's possible in Analytics, I have no idea, though):

1. Replace unconditionally:
   /(.*.aspx) --> /promotion/$1
2. Replace again:
   /promotion/promotion/(.*) --> /promotion/$1

If all else fails:

^/(?:[^p]|p[^r]|pr[^o]|pro[^m]|prom[^o]|promo[^t]|promot[^i]|promoti[^o]|promotio[^n])/(.*).aspx
