How to extract word from url with regex?

[youtuber]

Friends I want to get /autoit" or /autoit/ word from this source

Local $RegexSource[3] = ['href="https://www.autoitscript.com/forum/autoit/forum/" />', 'href="https://www.autoitscript.com/forum/autoit" />', 'href="https://www.autoitscript.com/forum/autoit" title="']

my regex pattern

$arrayregex = StringRegExp($RegexSource[$i], 'href="' & $aRegexDomain[0] & '.*forum/(.*?)(/[^/|"]+)', 3)

And my codes

Local $RegexSourceDomainName[3] = ['https://www.autoitscript.com/forum/', 'https://www.autoitscript.com/forum/autoit', 'https://www.autoitscript.com/']
Local $RegexSource[3] = ['href="https://www.autoitscript.com/forum/autoit/forum/" />', 'href="https://www.autoitscript.com/forum/autoit" />', 'href="https://www.autoitscript.com/forum/autoit" title="']

For $i = 0 To UBound($RegexSource) - 1
    $aRegexDomain = StringRegExp($RegexSourceDomainName[$i], 'https?://[^/]+', 3)
    $arrayregex = StringRegExp($RegexSource[$i], 'href="' & $aRegexDomain[0] & '.*forum/(.*?)(/[^/|"]+)', 3)

    If IsArray($arrayregex) Then
        ConsoleWrite($aRegexDomain[0] & " : " &$arrayregex[0] & @CRLF)
    EndIf
Next

and my console output

Getting that out of the URL would be easy, but the real question is what is the full scope of the code.

How do you expect it to work on other URLs?  what is going to be the common capture group you need?

Obviously this sees my work but this method is too long I want to do with Regex

#include <string.au3>
Local $RegexSourceDomainName[3] = ['https://www.autoitscript1.com/forum/', 'https://www.autoitscript2.com/forum/autoit', 'https://www.autoitscript3.com/']
Local $RegexSource[3] = ['href="https://www.autoitscript1.com/forum/autoit1/forum/" />', 'href="https://www.autoitscript2.com/forum/autoit2" />', 'href="https://www.autoitscript3.com/forum/autoit3" title="']

For $i = 0 To UBound($RegexSource) - 1
    $aRegexDomain = StringRegExp($RegexSourceDomainName[$i], 'https?://[^/]+', 3)
    $arrayregex = _StringBetween($RegexSource[$i], 'href="' & $aRegexDomain[0] & '/forum/','"')

    If IsArray($arrayregex) Then
        $arrayregex = StringReplace($arrayregex[0], "/forum/", "")
        ConsoleWrite($aRegexDomain[0] & " : " & $arrayregex & @CRLF)
        EndIf
Next

This shortens the code while getting the same results

#include <string.au3>
;~ Local $RegexSourceDomainName[3] = ['https://www.autoitscript1.com/forum/', 'https://www.autoitscript2.com/forum/autoit', 'https://www.autoitscript3.com/']
Local $RegexSource[3] = ['href="https://www.autoitscript1.com/forum/autoit1/forum/" />', 'href="https://www.autoitscript2.com/forum/autoit2" />', 'href="https://www.autoitscript3.com/forum/autoit3" title="']

For $i = 0 To UBound($RegexSource) - 1
    $s = StringRegExpReplace($RegexSource[$i], '(https?://[^/]+)/forum/' & '([^/"]+).*', "$1 : $2")
    ConsoleWrite($s & @CRLF)

;~     $aRegexDomain = StringRegExp($RegexSourceDomainName[$i], 'https?://[^/]+', 3)
;~     $arrayregex = _StringBetween($RegexSource[$i], 'href="' & $aRegexDomain[0] & '/forum/','"')

;~     If IsArray($arrayregex) Then
;~         $arrayregex = StringReplace($arrayregex[0], "/forum/", "")
;~         ConsoleWrite($aRegexDomain[0] & " : " & $arrayregex & @CRLF)
;~         EndIf
Next

But as said ViciousXUSMC  I really don't know how this could be used for a more general purpose
