Error when REGEX Match is empty

[FAB (Fabian Altendorfer)]

I have a question regarding REGEX-Matches. I loop through a Datatable which variables are empty sometimes. If they are empty, I get the error code “Object reference not set to an instance of an object” when trying to assign it to a variable. What is a good way to solve this? String.IsNullorEmpty doesn’t work properly.

Thanks a lot

Hi @FAB

You can try with ISMATCH activity

We can check with the Success Property if there was a match or not
With isNothing(YourVar) we can check if the variable is null or not

Hello.

You can validate, through the “Result”, if there is a match or not.
You can also put your regex sequence inside a try catch where in the catch you put the variable empty.

Thank you for your answers. Try Catch is a simple and good idea. I solved it this way.
