how to delete a specific part of a line from a text file - (Moved)

[JSBGAMES]

Hello guys
i need a little help with this scipt, i already managed to delete the blank lines from a text file but i also need to delete a part of the remaining lines.
example: "black tide: show me the way | 90003", I want to stay like this "| 90003"

#include <Array.au3>
Sleep (2000)
Local $rFile = (@ScriptDir & "\playlist.txt")
Local $aFile = FileReadToArray($rFile)
Local $wFile = FileOpen(@ScriptDir & "\playlist.txt",2)


For $i = 0 To UBound($aFile) -1 Step +1
    If $aFile[$i] <> "" Then
        Sleep(100)
        FileWriteLine($wFile,StringStripWS($aFile[$i],3))
    EndIf
Next

 

Lmp.au3Fetching info... playlist.txtFetching info...

?

$sFile = FileRead(@ScriptDir & "\playlist.txt")
$txt = StringRegExpReplace($sFile, '(?m)^(?|\h*\R|[^\|]+)|\h+$', "")
FileWrite(@ScriptDir & "\playlist2.txt", $txt)

Something like this if your file is to big to read then use filewriteline to write to a new file

stringmid and stringinstr can help to find first |

 

$hFile = FileOpen(@ScriptDir & "\playlist.txt", 0)

If $hFile = -1 Then
    MsgBox(0, "Error", "FileOpen failed check your file for existence")
    Exit
EndIf

;~ Read in lines of text until EOF
While 1
    $txtLine = FileReadLine($hFile)
    If @error = -1 Then ExitLoop
    If @error Then MsgBox(0, "Error", "FileReadLine returned @error to: " & @error)
    
    if ($txtLine <> "") then
        consolewrite(stringmid($txtLine,stringinstr($line,"|")))
    else
        ;~ its a blank line so do nothing
    endif
    
Wend
ConsoleWrite("EOF")
FileClose($hFile)

Thanks @mikell and @junkew

 

@mikell your example worked perfect for me, I just need it to be written in the same playlist.txt file or replacing the previous one
