Substitue Symbolic Derivative Term

I defined symbolic variables and function and took its derivative:
syms t x(t) xdot
A=sin(x);
diff(A,t)
This generated - D(x)(t)*cos(x(t))
Next I tried using the subs command to replace 'D(x)(t)' with xdot but didnt have any success. Does anyone know how to conduct this substitution? What is exact syntax?
Thanks!

What shows up if you use
evalin(symengine, 'PRETTYPRINT := FALSE');
feval(symengine, 'print', 'NoNL', diff(A,t))
