Need assistance in getting the coords from the Locate Command while using the "Execute Command and get output" block

As the title says, I'm planning to make an item that'll help in finding a certain structure in my mod, and I don't know how to get the raw coords from the output. Preferably two separate outputs for X and Z.

I'd assume maybe regex would do the trick? but I am extremely unfamiliar in regex and don't know how I would do so
