How to replace part of file?

[E1M1]

I wan't to make script that searcesh for

"minItemLvl = " and then replaces number after =. Only proplem is minItemLvl = 91 might be on diferent position (depends on file). Also number after = isn't always same.

How do I write function that searches for "minItemLvl = " and then replaces numberafter that? StringReplace Requires given string but I don't know what that number could be I know only that there is number after = but I don't know it's value.

Here's what I got while I was trying to find solution myself.

#Include <FileListToArray3.au3>
$FileList = _FileListToArray3(@scriptdir, "*", 1, 1,  1)
;~ minItemLvl = 91
for $i = 1 to 3
    $data =  FileRead($FileList[$i])
    $pos = StringInStr($data,"minItemLvl = ")
Next

What are you trying to replace the number with? That's important info in order to come up with a working solution. And your code as posted isn't going to work at all so we will be starting from scratch here.

EDIT: Also, does that line only appear once in each file or does it occur more than once?

I am trying to replace that number with number I want 10 for example.

Edit: I need to replace it only once in file.

I came up with this code:

#Include <FileListToArray3.au3>
$FileList = _FileListToArray3(@scriptdir, "*", 1, 1,  1)
;~ minItemLvl = 101
$files = ""
for $i = 1 to $FileList[0]
    $data =  FileRead($FileList[$i])
FileDelete($FileList[$i])
    FileWrite($FileList[$i],StringRegExpReplace($data,"minItemLvl = \d","minItemLvl = 10",1))
    ShellExecute($FileList[$i])
Next

But now 91 turned to 101 not 10

StringRegExpReplace($data,"minItemLvl = \d+","minItemLvl = 10", 1)

For $i = 1 To Ubound($fileList) -1
    $sStr = FileRead($filelist[$i])
    $sStr = StringRegExpReplace($sStr, "(?i)(minitem.+=)\s*\d+", "$1 " & $i, 1);; Here I'm just replacing it with $i but you can substitute your own method for determining the number
    If @Extended Then
        $hFile = FileOpen($filelist[$i], 2)
        Filewrite($hFile, $sStr)
        FileClose($hFile)
    EndIf
Next
