PowerShell Text File Edit

Question

Hello,

I have a subtitle file. The below is a sample of it which is a repetitve pattern but with different time and phrases. (note: it has 3 languages together each in a line).

112
00:06:53,04 --> 00:06:55,13
so afterwards I started reading books,
Tak jsem pak začala číst,
فبدأت أقرأ في كل الكتب

113
00:06:55,17 --> 00:06:57,04
all the books or most of them,
všechny knihy nebo většinu,
أو معظمها

Now i want to have 3 different files each has 1 language only. So, i want a code that will delete 2 lines of the selected languages, and leave me with single language i select.

Try this:

$FileName = $null,"c:\junk\Lang1.txt","c:\junk\Lang2.txt","c:\junk\Lang3.txt"  # $null is there so the inner loop's $_ can be used without subtracting 1
# Remove any old files
1..3 |
    ForEach-Object{
        Remove-Item $FileName[$_] -ErrorAction SilentlyContinue
    }

Get-ChildItem c:\junk\l.txt |
    Select-String -Pattern "^\d\d\d$" -Context 0,4 |
        ForEach-Object{
            $x = $_
            1..3 | ForEach-Object{ 
                $x.Line | Out-File $FileName[$_] -Append
                $x.Context.PostContext[0] | Out-File $FileName[$_] -Append  # timestamp?
                $x.Context.PostContext[$_] |Out-File $FileName[$_] -Append  # text
                "" |Out-File $FileName[$_] -Append                          # blank line
            }
        }
