I'm working on a script that processes XML files to manage metadata for my media collection. There's a specific line generated by my creation tool that I want to remove after the fact. My current code aims to find and replace the `` tags, but the challenge arises because sometimes the line looks like `Some Name` and sometimes it includes multiple names separated by pipes, like `One Name|Another Name`. I need to figure out how to handle both cases. Here's what I have so far:
```powershell
If (Select-String -Path $File -Pattern "<Writer>.*</Writer>") {
$Line = Get-Content $File | Select-String "<Writer>" | Select-Object -ExpandProperty Line
$NewLine = " <Writer></Writer>"
$Content = Get-Content $File
$Content -Replace $Line,$NewLine | Set-Content $File
}
```
Any tips on managing this? Thanks!

Since you're working with XML, consider using an XPath query with Select-Xml instead of relying on regex. It can give you more control and precision when targeting that specific tag and its contents.
To deal with that `` tag, try checking if the string contains a pipe and split it accordingly. You can then incorporate logic to handle those multiple names. Just make sure to join the names back together excluding the ones you want to drop. It might look something like this in your code.
So you're suggesting I split the string at the pipe and then rejoin it? Got it, but what about when there are several pipes?
I hear you on that, but I'm trying to keep it simple with just PowerShell without adding another language to the mix.
