How do I use PowerShell to Validate XML files against an XSD?

Question

As a part of my development I\'d like to be able to validate an entire folder\'s worth of XML files against a single XSD file. A PowerShell function seems like a good candid

I am using this simple snippet, always works and you don't need complicated functions. It this example I am loading configuration xml with data which are used later for deployment and server configuration:

# You probably don't need this, it's just my way
$script:Context = New-Object -TypeName System.Management.Automation.PSObject
Add-Member -InputObject $Context -MemberType NoteProperty -Name Configuration -Value ""
$ConfigurationPath = $(Join-Path -Path $PWD -ChildPath "Configuration")

# Load xml and its schema
$Context.Configuration = [xml](Get-Content -LiteralPath $(Join-Path -Path $ConfigurationPath -ChildPath "Configuration.xml"))
$Context.Configuration.Schemas.Add($null, $(Join-Path -Path $ConfigurationPath -ChildPath "Configuration.xsd")) | Out-Null

# Validate xml against schema
$Context.Configuration.Validate(
    {
        Write-Host "ERROR: The Configuration-File Configuration.xml is not valid. $($_.Message)" -ForegroundColor Red

        exit 1
    })
