How to detect know and unknow strings with StringRegExp?

[Malkey]

This example matches the first two occurrences of "85C0741A68??????1068??????1068??????108BC8E8",  then, only on the third occurrence, replaces "85C0741A68" in "85C0741A68??????1068??????1068??????108BC8E8" with "85C0EB1A68".

You should be able to figure out the RE pattern by studying the StringRegExp and StringRegExpReplace functions in the Autoit  help file.

#include<array.au3>

$data = "abc85C0741A68??????1068??????1068??????108BC8E8w " & _
        "def85C0741A68??????1068??????1068??????108BC8E8x " & _
        "gfi85C0741A68??????1068??????1068??????108BC8E8y " & _
        "jkl85C0741A68??????1068??????1068??????108BC8E8z " & _
        "85C0741A68??????1068??????1068??????108BC8E8 " & _
        "85C0741A68??????1068??????1068??????108BC8E8 " & _
        "85C0741A68??????1068??????1068??????108BC8E8 " & _
        "85C0741A68??????1068??????1068??????108BC8E8 " & _
        "85C0741A68??????1068??????1068??????108BC8E8 " & _
        "85C0741A68??????1068??????1068??????108BC8E8 " & _
        "85C0741A68??????1068??????1068??????108BC8E8 " & _
        "85C0741A68??????1068??????1068??????108BC8E8 " & _
        "85C0741A68??????1068??????1068??????108BC8E8 " & _
        "85C0741A68??????1068??????1068??????108BC8E8 "


;$p = StringRegExpReplace($data, "^.*?(85C0741A68.{6}1068.{6}1068.{6}108BC8E8.*?85C0741A68.{6}1068.{6}1068.{6}108BC8E8.*?)(85C0741A68)(.{6}1068.{6}1068.{6}108BC8E8)", "${1}85C0EB1A68${3}")

; Or

Local $iReplaceOccurrenceNumber = 3

$p = StringRegExpReplace($data, "^(.*?(?:85C0741A68.{6}1068.{6}1068.{6}108BC8E8.*?){" & $iReplaceOccurrenceNumber - 1 & "})(85C0741A68)(.{6}1068.{6}1068.{6}108BC8E8)", "${1}85C0EB1A68${3}")
ConsoleWrite($p & @LF)
