About Expression Rule Functions

I have three CDTs that contain some fields with the same value.

I want to create an expression rule that matches them and extracts only the fields that don't overlap.

What function can I use to make it?

Use symmetricdifference() function.

a!localVariables(
  local!a: {1,2,3,4,5},
  local!b: {1,2,6,7,8},
  symmetricdifference(local!a,local!b)
)

O/P:

List of Number (Integer) - 6 items

3(Number (Integer))
4(Number (Integer))
5(Number (Integer))
6(Number (Integer))
7(Number (Integer))
8(Number (Integer))

Thank you for your reply.
However, because there are many fields in the CDT, it would be difficult to write an array.Is there any other way to achieve this without using an array?
For example, how to use the type! function to call the CDT and extract fields that are not duplicates.
