getting one field data using other field in struct

Hello, I have a structure

I want to get the data of 2nd field but not using app.temp.Channel(2).data

I want to use the name field instead.

something like

mydata = app.temp.Channel.data(app.temp.Channel.name == 'U1');

but I have error (Error using == ; Too many input arguments).

May I know some suggestions, How to do this in a simple manner without using complex for loops.
