Return second object in array

Question

Say I have an output like below, what function could I use to ouput only the first (A) and third (C) elements?

[
  "A=testA",
  "B=testB",
  "C=testC",
  "D=testD",
  "E=testE"
]

Answer 1

@Jan de Mul Thanks for reaching out. You can access the elements in below ways either through loop or directly through expression.

1. Let's say you have stored the output in a variable named "arritems". You can access the value of third item in Compose Action using below expression.

      @variables('arritems')[2]
   

2. Another way is to loop through the arritems using foreach loop by inputting the arritems variable and with compose action you can access each element using below expression.

      @items('For_each')
   

Here is sample logic app code reference with the above mentioned examples.
