HI man, great video! Do you know how to go deeper into the database tree? In your case, you are accessing root/text. I would like to access root/child1/child2 and print one of three values stored in there. None of my ideas work. Any ideas? :D
It's been a year. You've probably figured it out. But for others who have the same issue. This tutorial is definitely going to help: th-cam.com/video/b1ULt_No3IY/w-d-xo.html
