The best is if you show what you have tried so far rather than
"something didn't work" because the devil is in the detail - there are
several ways things may be going wrong for you.
Also, please say which toolkit you are using.
All these are about a "complete, minimal example" -- something that can
be run, illustrates the issue and is no larger than necessary, together
with a description of what is the desired results.

and I want to read labels. But, all I got is empty string, or null
value. Could someone please write a simple query which is going to read
anything from this example?
Thank you!
