Simple question for all you experts:

String A: "I like cherries, apples, berries"
String B: "I like cherries, apples, berries, cookies"

I would like to find the text in string B but not String A(the odd one out)

I am trying to find-> ", cookies"

Is there an AppleScript that can solve this for me?

    That would be the difference, not the intersection. – CJK Mar 25 '18 at 22:25

In the absence of any other examples or formal criteria for how matching ought to be performed, I've just given an example here of the simplest way to obtain the difference between two strings:

    set A to "I like cherries, apples, berries"
    set B to "I like cherries, apples, berries, cookies"


    set the text item delimiters to {null, A}

    return text items of B as text --> ", cookies"

This works if one string is contained entirely within (i.e. is a substring of) the other, as was the case with your given strings. If string A were to be `"But I like cherries, apples, berries" or "I like cherries, apples, berries.", the above method will not work.

It also won't work if string B contains the word "null" where string A does not.

Here is another option...

set stringA to "I like cherries, apples, berries"
set stringB to "I like cherries, apples, berries, cookies"
set stringACharacters to count of text items of stringA

set oddManOut to text -1 thru (stringACharacters + 1) of stringB

Here is another way, while using AppleScript's do shell script command, and awk:

set strA to "I like cherries, apples, berries"
set strB to "I like cherries, apples, berries, cookies"

do shell script "awk -F" & quoted form of strA & " '{print $2}'<<<" & quoted form of strB

When run in Script Editor, with (Events) (Replies) selected in the [Event Log], it outputs:

tell current application
    do shell script "awk -F'I like cherries, apples, berries' '{print $2}'<<<'I like cherries, apples, berries, cookies'"
        --> ", cookies"
end tell

Result:
", cookies"

Note: The example AppleScript code is just that and does not employ any error handling and is meant only to show one of many ways to accomplish a task. The onus is always upon the User to add/use appropriate error handling as needed/wanted.
