How can I tag a feature that matches a class but does match a link?

Hello! 

I have a table in which one of the columns opens a different page, while all other open a pop-up window. I want to track whenever a user opens a pop-up, so I need to tag the feature as all elements from the table (a.ant-table-row), except the ones who link to another page ([hrefª="/event/"]). I have tried to use .ant-table-row:not([href^="/event/") but it says that this rule is not accepted. Is there any alternative or is this approach simply not supported?
