MS Flow - Elements contained in text



I have an issue where I need some help. My issue is as follows:

1. I have a string variable that contains some text. 


Blablabla 12345, 22222

2. Then I have another string that I extracted from an array. 


12345, 22222, 98909



I want to check whether the elements from no 2 are contained in no 1


There are too many combinations. As an example, I can exact 12345 from no 2 and then find that this is included in no 1. But then I want to know if also 22222 is included in no 1 and also the third element. It might be the case that only 22222 is included in no 1 or 22222 and 98909 but not 12345.



Is there a smart way to check which of the elments from no 2 are included in no 1 with the help of MS Flow?


Would be great if somebody could help.

Many thanks in advance.

Re: MS Flow - Elements contained in text

Hi @lreinhard7 


What you can do is, you already have two arrays. 

lets us name them as Array 1 and Array 2. 

You want to check what all elements of array 2 are included in array 1. 


First, initialise a 3rd array and leave the value blank. Now add an action apply to each and in this put the array2. within the apply to each, add a condition and on the left put the array 1 and the operator will be contains and on the right side put current item. In the yes branch add an action -> append to array variable and then select the third varaiable name and the value is current item. 


This way you will get all the elements of array 2 contained in array 1 in the array 3. You can create an array 4 and put that in the no branch to get the elements of array 2 that are NOT contained in array 1. Makes sense?


Hope this Helps!
