Create structure path from string and cell array

I have a nested structure called S. The data I want to access is in:

S.Signal_00.values.y_values

The path always stays the same but the values for Signal_00 differs. I have these Signal names stored in a cell array like below.

sigNames = {'Signal_00'; 'Signal_01';'Signal_02'...}

How do I create the above structure path using the Signal names I have stored in the cell array sigNames?

Let me clarify , do you want to access the data from structure using sigNames??

Yes, that's correct.
