So I am able to see if the string contains the text, is there a way to search the string, find the lines that contain that text, then display it?

Example
Code:
[20:15:07] Matt Cross has left the server (timeout).

[20:15:12]  County General Hospital has reported Andre Payne as a wanted person.

[20:15:21] DISPATCH: Michael Clarkson has impounded Jimmy Strong's Tahoma ($0 unpaid tickets).

[20:15:30] ** (CHP) CHP-36 : CHP-36 enroute to LAPD HQ, OCCx1, charged with Driving without a license. **

[20:15:30] (radio) Andrew Powers says: (radio) CHP-36 enroute to LAPD HQ, OCCx1, charged with Driving without a license.

[20:15:44] * Andrew Powers uses their remote to open the gates.
That is in a string, I have it displayed in a text box, and it's each on it's own line, I'd like to preserve that.

What I need to do is set another textbox to those three lines, but no the other lines that don't contain "Andrew Powers" (I've declared a textbox as a string so it can be inputted)

Thanks!
