using PowerShell, Is there an easier or better optimized way to get the download link to the latest Nvidia Driver?

Question

Hello all, I've been able to get this code to get the latest download link for Nvidia Driver for a Quadro P1000.
I was wondering, if there's a better way to do this.

Here's my code:

#Get Nvidia Drivers
            #This next section is JUST TO get the LINK to the LATEST driver from Nvidia
            #WebContent gets the links that are "href" from the nvidia JS request. No idea if there's an easier wey to get this.
            $Webcontent = (Invoke-WebRequest 'https://www.nvidia.com/Download/processFind.aspx?psid=73&pfid=842&osid=57&lid=1&whql=&lang=en-us&ctk=0&qnfslb=10&dtcid=0').links.href 
            #The following line uses Regex regular expressions to MATCH and RETRIEVE ONE single value from the list of values in the previous line.
            $NVIDIALinkToLatestDriver = [regex]::Match($Webcontent, '//(www.nvidia.com/download/driverResults.aspx/[0-9]*/en-us)').Groups[1].Value
            #Link after the previous crap
            $NVIDIADLPage = New-Object -COM "HTMLFile" #Creates a COM Object for easier search of the link.
            [string]$htmlBody = (Invoke-WebRequest -Uri $NVIDIALinkToLatestDriver -UseBasicParsing).Content #Parses the content of the landing page to then look by id
            $NVIDIADLPage.write([ref]$htmlBody)
            $replace = [regex]::Replace($NVIDIADLPage.getElementById('lnkDwnldBtn').href, 'about:', 'www.nvidia.com') #Replaces the "about" with "www.nvidia.com"
            $Webcontent = (Invoke-WebRequest $replace) #Replace Webcontent with the latest link.
            [String]$NvidiaLinkToExe = $Webcontent.links.href -match ".*.exe$" #On this link there's the exe file for Nvidia Drivers
            $NvidiaLinkToExe = $NvidiaLinkToExe -replace "^", "http:" #Replace start of line with the correct Nvidia Link.
            Remove-Variable -Name NVIDIADLPage, Webcontent, replace -Force #cleanup of the previous mess.
            if ($NvidiaLinkToExe -match 'http:\/\/.*[0-9]{2}\/(([0-9]{3}\.[0-9]{2}).*\.exe)') {
                $NVIDIAExeToDownload = [PSCustomObject]@{
                    Url     = $Matches[0];
                    Name    = $Matches[1];
                    Version = $Matches[2]
                }
            }

As you can see, I have to create three Invoke-WebRequest just to get one link. And, I think I made no use of piping, because I was unable to make it work.

Thanks!

Your code seems better than mine. I had to call Invoke-WebRequest 3 times to get the link as well and once more to download it.

$destination = 'C:\Temp'
$downloadlist = 'https://www.nvidia.com/Download/processFind.aspx?psid=73&pfid=842&osid=57&lid=1&whql=&lang=en-us&ctk=0&qnfslb=10&dtcid=0'

$pattern = "(?s)<tr>.+?href='//(?<URL>.+?)'>.+?<td.+?>(?<Version>.+?)</td.+?td.+?>(?<Date>.+?)</td.+</tr>"
$content = Invoke-WebRequest $downloadlist -UseBasicParsing

$download = if($content.RawContent -match $pattern){
    [PSCustomObject]@{
        URL     = $Matches.URL
        Version = $Matches.Version
        Date    = $Matches.Date
    }
}

$pattern = '(?s)(?<Package>/content/driver[^"]+?{0}/.+?)(?=")' -f ($download.Version -replace '.+\(|\)')
$content = Invoke-WebRequest $download.url -UseBasicParsing

if($content.RawContent -match $pattern){
    $pattern = '//(?<Package>.+?{0}.+exe)' -f ($download.Version -replace '.+\(|\)')
    $content = Invoke-WebRequest -Uri "https://www.nvidia.com$($Matches.Package)" -UseBasicParsing

    if($content.RawContent -match $pattern){
        Invoke-WebRequest "https://$($Matches.Package)" -OutFile (Join-Path $destination $($Matches.package -replace '.+/'))
    }
}

If you just want the link and other info you can drop the fourth.

$downloadlist = 'https://www.nvidia.com/Download/processFind.aspx?psid=73&pfid=842&osid=57&lid=1&whql=&lang=en-us&ctk=0&qnfslb=10&dtcid=0'

$content = Invoke-WebRequest $downloadlist -UseBasicParsing

$download = if($content.RawContent -match "(?s)<tr>.+?href='//(?<URL>.+?)'>.+?<td.+?>(?<Version>.+?)</td.+?td.+?>(?<Date>.+?)</td.+</tr>"){
    [PSCustomObject]@{
        URL     = $Matches.URL
        Version = $Matches.Version
        Date    = $Matches.Date
    }
}

$pattern = '(?s)(?<Package>/content/driver[^"]+?{0}/.+?)(?=")' -f ($download.Version -replace '.+\(|\)')
$content = Invoke-WebRequest $download.url -UseBasicParsing

if($content.RawContent -match $pattern){
    $pattern = '//(?<Package>.+?{0}.+exe)' -f ($download.Version -replace '.+\(|\)')
    $content = Invoke-WebRequest -Uri "https://www.nvidia.com$($Matches.Package)" -UseBasicParsing

    $download.URL = "https://$($Matches.Package)"
    $download
}
