Comparing List of Strings

Hello ,

Currently have a flow that he output is the list of string below. I have my own list and need to compare it to the list of arrays below. Is this possible in Power automate and if anyone can get me started on how to build it, it would be greatly appreciated. 

 

I tried to use the conditional statement like this Hello3 > is equal to > Output_String. I dont want to use "contain' because if not it will return true for hello, hello2, hello3, hello4 not just Hello3.

 

My_list:

Hello3

Morning2

 

need to compare against this output below

 

Output_String:

[

[],

['Hello',

'Hello2,

'Hello3',

'Hello4],

['Morning',

'Morning2',

'Moring3]

]

    Ah... sure, sorry, I use the union function on arrays with the same array to get unique values.

     

    You will have to go the first route I gave you.

    I think he was trying to check if a different array which consists of Hello3 or morning2 then return true or false.

     

    ['Hello',

    'Hello2,

    'Hello3',

    'Hello4],

    [],

    ['Morning',

    'Morning2',

    'Moring3]

    ]

     

    not join two arrays...

    Re: Comparing List of Strings

    You can do the following complicated version:

    Create an array variable.

    Then you use the use the filter array function inside a for each loop on one of your arrays and compare against each item of the other array, if the element is found you use the append to array function and add the element.

     

    Or you go the simple route and use an expression with the union function inside a compose action:

    union(outputs('ComposeArray1'),outputs('ComposeArray2'))
