Comparing Arrays

[Tapes]

So I have a hopefully not too complicated question!
I have three arrays right now that are declared. Two txt files have been Read into two of these arrays seperately.I am comparing the two Arrays to decipher the differences between the two.If there is a difference, I am outputing the string that can't be found into the third array (Array3). The third Array is then written back into a new text file.

For example lets say this is what my arrays looks like.

Array2 should be the correct texts, while Array1 may have some variances.

Array 1 = "text1,text2,text3,text4"
Array 2 = "text1,text2,text3,text5"

My third Array would then output
Array 3 = "text4"

This is what I have working right now, but I am trying to achieve a script more complicated.

The two Arrays should normally be the same, but I need to check for differences. These differences may include different version of files, and missing files.

The two Arrays should normally look exactly the same, but I need to check for different versions and missing strings.Array2 should be the correct versions and string, while Array1 may have some variances.

Lets say these are how the Arrays look now
v = version

Array1 = "text1V1,text2V1,text3V2"
Array2 = "text1v1,text2v1,text3v1,text4v1"

Output of:

Array 3 = " Missing ) text4v1, Wrong Version) text3v2"

I want the output to tell me that text4v1 is "MISSING" from the first Array, and that text3v2 is the "WRONG VERSION". I am having trouble writing code to differentiate between cases. My code of what I have right now is shown below.

expandcollapse popup

Global $Array1, $Array2,$Array3

$File1 = "Path of text file"
$File2 = "Path of text file"

_FileReadToArray($File1, $Array1)
_FileReadToArray($File2, $Array2)

If IsArray($Array1) Then
     $iMax = UBound($Array1); get array size
EndIf


For $i = 1 to $iMax-1
    _ArraySearch($Array2, $Array1[$i])
    If @error Then
        _ArrayAdd($Array3, $Array1[$i])
    EndIf
Next

_FileWriteFromArray("Results.txt", $Array3)



I've tried adding the *** line to the for loop, but that didn't work either.
For $i = 1 to $iMax - 1
   
    _ArraySearch($Array1, $Array[$i])
If @error Then
        If NOT($Array2[$i] == $Array1) Then
    ***     _ArrayAdd($Array3, "Missing) " & $Array2[$i])
            ;_ArrayAdd($Array3, "test")
        Else
        _ArrayAdd($Array3, "Wrong Version) " &  $Array2[$i])
        EndIf
    EndIf
Next

Sorry still learning AutoIt, so hopefully I didn't explain it too confusingly!

Tapes,

This seems to work correctly when I test:

expandcollapse popup

#include <Array.au3>

;Global $Array1, $Array2, $Array3

;$File1 = "Path of text file"
;$File2 = "Path of text file"

;_FileReadToArray($File1, $Array1)
;_FileReadToArray($File2, $Array2)

; Simulate reading in files
Global $Array1[4] = [3, "text1V1", "text2V1","text3V2"]
Global $Array2[5] = [4, "text1v1", "text2v1", "text3v1", "text4v1"]
Global $Array3[1] = [0]

For $i = 1 To $Array2[0]
    ; Extract the text# part
    $sItem = StringRegExpReplace($Array2[$i], "(?i)^(.*)v.*$", "$1")
    ; Check if it exists in Array1
    $iIndex = _ArraySearch($Array1, $sItem, 0, 0, 0, 1)
    If $iIndex = -1 Then
        ; It does not so add to Array3
        $Array3[0] += 1
        ReDim $Array3[$Array3[0] + 1]
        $Array3[$Array3[0]] = "Missing ) " & $Array2[$i]
    Else
        ; It does so check version
        If $Array1[$iIndex] <> $Array2[$i] Then
            ; And add to Array3 if wrong
            $Array3[0] += 1
            ReDim $Array3[$Array3[0] + 1]
            $Array3[$Array3[0]] = "Wrong Version ) " & $Array1[$iIndex]
        EndIf
    EndIf
Next

_ArrayDisplay($Array3)

All clear?

Thank you for answering! I will give this a try and let you know If it works!
