Sorry, I forgot the "\" at the end. It should be: /^\{[a-zA-Z]+\.[a-zA-Z]+\.[a-zA-Z]+\}$/gm. However it is still not working ...

Isn't this enough?

{[a-zA-Z]+\.[a-zA-Z]+\.[a-zA-Z]+}

Or even this?

{[^}]+}

Dear Paul, 

You made my day. 

It is working perfectly. I add ^ and $ to avoid strings that have additional content.

I was hoping to set all matches as "validated", but I have to click them one by one. 

Do you have an idea how I could solve this?

At any rate, many thanks!

Glad that helped.  For Passolo expertise itself you will need some proper help ;-)  Maybe Achim Herrmann  or Adrian Maniu can help you with that?

Thanks, Paul. I hope they can help :-)

Using the Find function is not a good choice if you want to set all entries found to validated. Entries found by this function will be shown in the Output window and you need to step through them one by one.

The better choice is a Filter, because you then can select all filtered entries and then validate them in one single step. Filtering doesn't directly support RegEx, you can either use the BASIC engine to create a filter or implement a callback with your own filtering routine based on RegEx. 

Dear Achim, 

Yes, I agree. However, given that filtering does not support RegEx directly and the Basic engine is not returning the results I want, the only solution is to write a macro that calls up the RegEx. And I am not good at that. So, I am stuck at the moment. 

Thanks!
