# Requires -Version 3 Function Get-VcList { <# .SYNOPSIS Returns an array of Visual C++ Redistributables. .DESCRIPTION This function reads the Visual C++ Redistributables listed in an internal manifest or an external XML file into an array that can be passed to other VcRedist functions. A complete listing the supported and all known redistributables is included in the module. These internal manifests can be exported with Export-VcXml. .OUTPUTS System.Array .NOTES Name: Get-VcXml Author: Aaron Parker Twitter: @stealthpuppy .LINK https://github.com/aaronparker/Install-VisualCRedistributables .PARAMETER Xml The XML file that contains the details about the Visual C++ Redistributables. This must be in the expected format. .PARAMETER Export Defines the list of Visual C++ Redistributables to export - All Redistributables or Supported Redistributables only. Defaults to exporting the Supported Redistributables. .EXAMPLE Get-VcList Description: Return an array of the Visual C++ Redistributables from the embedded manifest .EXAMPLE Get-VcList -Xml ".\VisualCRedistributablesSupported.xml" Description: Return an array of the Visual C++ Redistributables listed in VisualCRedistributablesSupported.xml. #> [CmdletBinding(SupportsShouldProcess = $False)] [OutputType([Array])] Param ( [Parameter(Mandatory = $False, Position = 0, HelpMessage = "Path to the XML document describing the Redistributables.")] [ValidateNotNull()] [ValidateScript({ If (Test-Path $_ -PathType 'Leaf') { $True } Else { Throw "Cannot find file $_" } })] [string]$Xml = "$($MyInvocation.MyCommand.Module.ModuleBase)\VisualCRedistributablesSupported.xml", [Parameter(Mandatory = $False)] [ValidateSet('All', 'Supported')] [string]$Export = "Supported" ) Begin { Switch ($Export) { "All" { $Xml = "$($MyInvocation.MyCommand.Module.ModuleBase)\VisualCRedistributablesAll.xml" Write-Warning "This array includes unsupported Visual C++ Redistributables." } } # The array that will be returned $Output = @() } Process { # Read the specifed XML document Try { Write-Verbose "Reading XML document $Xml."
