How to acess the Data of a struct with a variable

for example a struct contains another struct and I want to acess the content of the second struct the struct looks like:

Data.Sens1.current=[2]
Data.Sens2.current=[4]
Data.Sens3.current=[5]
... 
Data.Sensn.current =[9]

now i want to assign the content of the Sensors to anothe variable. i can do it this way

data(1)=Data.Sens_one.current
data(2)=Data.Sens_two.current

this way is very laborious. Is there an easy way to assign the Content of a struct with a for queue and set Sens_one.current, Sens_two.current ... as a char vector. this was doesn't seem to work

    sens_vector=['Sens_one.current';'Sens_two.current';'Sens_two.current';...]
    for i=1:n
    date(i)=Data.(sens_vector(i,:))
    end

I can only acess the Date in the inner struct with structName.(dynamicExpression) like the matlap help "Generate Field Names from Variables" here in my example

A=['current']
data.Sens1.(A)

but this way doesn't seem to work if I want to acess the first struct like

A=['Sens1.current']
data.(A)

Can I acess the Data my way or does anyone know another way? Thanks in advance

   fn = fieldnames(Data);
   for K = 1 : length(fn)
     thisfield = fn{K};
     sensnum = str2double( regexp(thisfield, '\d+', 'match') );
     data(sensnum) = Data.(thisfield).current;
   end

You could probably also do something with struct2cell

      Data.Sens1.current=[2]
      Data.Sens2.current=[4]
      Data.Sens3.current=[5]
      Data.Sens4.current =[6]
      Data.Sens5.current =[7]
      Data.Sens6.current =[8]
      Data.Sens7.current =[9]
      Data.Sens8.current =[10]
      Data.Sens9.current =[11]

      %cellfun + Dynamic Structure Naming
      arrayOut = cellfun(@(nameIn)(Data.(nameIn).current),fieldnames(Data));

     arrayOut'
     %  ans =
     %    2     4     5     6     7     8     9    10    11
