How to run PowerShell, as a Batch Process file txt/html with REGEX (search and replace)?

Question

hello. I have more regex to run on multiple html files from Folder1. I must run more REGEX with search and replace, for example:

SEARCH: (?-s)(".+?") REPLACE BY: $0
SEARCH: (^.*?)=(.*$) Replace by: \1\r\n\2
SEARCH: ^.(.*)$ REPLACE BY: \1

I mage a PowerShellp script, I add those 3 regex search and replace formulas, but is not working. Can anyone help me?

$sourceFiles = Get-ChildItem 'c:\Folder1'  
$destinationFolder = 'c:\Folder1'
foreach ($file in $sourceFiles) {
$sourceContent = Get-Content $file.FullName -Raw

$contentToInsert = [regex]::match($sourceContent,"(?-s)(".+?")").value
$destinationContent = Get-Content $destinationFolder\$($file.Name) -Raw
$destinationContent = $destinationContent -replace '$0',$contentToInsert

$contentToInsert = [regex]::match($sourceContent,"(^.*?)=(.*$)").value
$destinationContent = Get-Content $destinationFolder\$($file.Name) -Raw
$destinationContent = $destinationContent -replace '\1\r\n\2',$contentToInsert

$contentToInsert = [regex]::match($sourceContent,"^.(.*)$").value
$destinationContent = Get-Content $destinationFolder\$($file.Name) -Raw
$destinationContent = $destinationContent -replace '\1',$contentToInsert

Set-Content -Path $destinationFolder\$($file.Name) -Value $destinationContent -Encoding UTF8
} #end foreach file

Answer 1

got it. This is the solution:

$path = 'c:\Folder1\file1.html'
$result = 'c:\Folder1\result.html'
Get-Content -Path $path | ForEach-Object{ 
    $one = $_ -replace '(?<=<li>)\s+','CARPET' #replace First Regex with the word CARPET
    $two = $one -replace 'CARPET','DOOR' #replace the word CARPET with DOOR
    ($three = $two -replace 'DOOR','BEAUTIFUL') | Out-File -FilePath $result -Append #replace the word DOOR with BEAUTIFUL
    "Final = $three"
}

Ok, so I have this lines on File1.html

<ul id="sidebarNavigation">
<li><a href="https://mywebsite.com/page-1.html"; title="Page 1">Page 1 (34)</a></li>
<li> <a href="https://mywebsite.com/page-2.html"; title="Page 2">Page 2 (29)</a></li>
<li><a href="https://mywebsite.com/page-3.html"; title="Page-3">Page 3 (11)</a></li>
</ul>

@Rich Matheisen I made an update on your last code, just for using 2 regex formulas

$path = 'c:\Folder1\file1.html'  
$result = 'c:\Folder1\result.html'  
Get-Content -Path $path | ForEach-Object{   
       $one = ($_ -replace '(?<=<li>)\s+','CARPET')   | Out-File -FilePath $result -Append      
       ($two = $one -replace 'CARPET','DOOR')   | Out-File -FilePath $result -Append   
'Final = $two'  
     }  

The PowerShell code seems to be good, but the problem is that the second regex, on the $two doesn't make the replacement from CARPET to DOOR. I don't know why.

nope. It duplicates my lines. This is how the output should look like result.html:

<ul id="sidebarNavigation">
<li><a href="https://mywebsite.com/page-1.html"; title="Page 1">Page 1 (34)</a></li>
<li>DOOR<a href="https://mywebsite.com/page-2.html"; title="Page 2">Page 2 (29)</a></li>
<li><a href="https://mywebsite.com/page-3.html"; title="Page-3">Page 3 (11)</a></li>
</ul>

P.S. in Powershell screen/terminal looks good. But in the result.html it doesn't look good.
