Remove Items Broken Links due to the item being unkown

Question

Is it possible to removed broken links using sitecore powershell. I checked the items link in the Navigation > Links and some of them has "Not found: master {GUID}".

Here is the sample code I have that will fetch the links but it will an error because the linkedItem doesn't exist.

$page = Get-Item -Path $SearchParentPath
$links = Get-ItemReferrer -Item $page -ItemLink

# Iterate through referring items
foreach ($link in $links) {
    $linkedItem = Get-Item -Path "/sitecore" -ID $link.SourceItemID
    if ($linkedItem -eq $null) {
        Write-Host "Broken Link $($link.SourceItemID)"
    }
}

Answer 1

Instead of calling Get-Item, use Test-Path command.

It will return either true or false depending on whether the item with given ID exists:

$page = Get-Item -Path $SearchParentPath
$links = Get-ItemReferrer -Item $page -ItemLink

# Iterate through referring items
foreach ($link in $links) {
    $exists = Test-Path $link.SourceItemID.ToString()
    if (!$exists) {
        Write-Host "Broken Link $($link.SourceItemID)"
    }
}
