PARSING: Copy lines from several files into a single point of other html files

hello, maybe someone can help me. I have a lot of html files in Folder-1 and the same number of files in Folder-2. The name of the files is the same on both folders, only the content of them is different. As you can see in this image what I want to do is to copy the lines from <!--START--> to <!--FINNISH --> and paste them to other files from second folder, in html files, in the point PUT-HERE-THE-CODE

You have to know that the content of <!--START--> to <!--FINNISH --> is different on all pages, so only this 2 words are repeated in all files, the links are different. And in the Folder-2, the only part that repeats in all files is PUT-HERE-THE-CODE

This are the code lines from both files:

    I find The solution: Thanks for regex.

    $sourceFiles = Get-ChildItem 'c:\Folder1'  
    $destinationFolder = 'c:\Folder2'
    
    foreach ($file in $sourceFiles) {
    
    $sourceContent = Get-Content $file.FullName -Raw
    $contentToInsert = [regex]::match($sourceContent,"(?ms)\<!--START--\>(.+)\<!--FINNISH --\>").value
    $destinationContent = Get-Content $destinationFolder\$($file.Name) -Raw
    $destinationContent = $destinationContent -replace 'PUT-HERE-THE-CODE',$contentToInsert
    
    Set-Content -Path $destinationFolder\$($file.Name) -Value $destinationContent -Encoding UTF8
    
    } #end foreach file

    I'll leave you to deal with getting the file names and directories into the code, but this pair of regular expressions should do the replacement:

    $f1text = get-content .\f1.txt -raw
    $f2text = get-content .\f2.txt -raw
    $f3text = ""
    if ($f1text -cmatch "(?ms)\<!--START--\>(.+)\<!--FINNISH --\>"){
        $p = $Matches[1]
        if ($f2text -cmatch "(?ms)PUT-HERE-THE-CODE"){
            $f3text = $f2 -creplace "PUT-HERE-THE-CODE", "$p"
        }
    }

    Thank you, yes, but your code will make a replacement only in 2 files, f1.txt and f2.txt. But I have 1300 files in Folder-1 and 1300 files in Folder-2. So I want to change all at once. How can I do that ?
