GA 不支持正则表达式

Question

I am using the following RegEx (check on different RegEx checkers online, on which it works):

^((?!pro).)*$

However, GA gives me an error: Invalid regular expression Your data request includes an invalid regular expression.

The line I am trying to exclude is: xx-pro-xxx-xxx

I have read through the documentation Google provides, but cannot seem to find why it is not working.

Does anybody know what the problem is and how to solve it?

Answer 1

GA doesn't seem to support lookeheads ( (?!...) ), so you can't use that regex. Maybe there is a way to use .{2}-pro-.{3}-.{2} in a negative condition, ie "don't use strings that match this pattern"?

General advice - every regex engine is different and supports different set of operators. It's not enough to check regex on other engines
