Channel 9 PowerShell Download Script for Build 2014 Videos

Crazy long title, but you get the idea.

Here is a PowerShell script that will download all of the mp4 high quality videos from Channel 9 for Build 2014.

Change the $baseLocation to a folder of your choosing, and let it go.

$baseLocation = "V:/Coding/Channel 9/Build 2014/"
$rssFeed = New-Object -TypeName XML

$rss = (New-Object System.Net.WebClient).DownloadString("http://s.ch9.ms/Events/Build/2014/RSS/mp4high")
$rssFeed.LoadXml($rss)
$itemCount = $rssFeed.rss.channel.item.Count

for($i = 0; $i -lt $itemCount; $i++) {
    $fileCount = $i + 1
    Write-Progress -Activity "Downloading Recordings..." -Status "Processing file $fileCount of $itemCount" -PercentComplete (($i/$itemCount)*100)
    $item = $rssFeed.rss.channel.item[$i]
    $fileExtension = $item.enclosure.url.Substring($item.enclosure.url.lastIndexOf('.'), $item.enclosure.url.length - $item.enclosure.url.lastIndexOf('.'))
    $cleanFileName = [RegEx]::Replace($item.title, "[{0}]" -f ([RegEx]::Escape([String][System.IO.Path]::GetInvalidFileNameChars())), '') 
    $downloadTo = $baseLocation+$cleanFileName+$fileExtension
    
    If(!(Test-Path $downloadTo)) {
        (New-Object System.Net.WebClient).DownloadFile($item.enclosure.url, $downloadTo)
    }
}
