Get HP Driver Pack Info with PowerShell – Web Scraping Method

So I was preparing an OSD task sequence in ConfigMgr to deploy Windows 10 1909 and I wanted to know if any of the HP workstations I would be deploying to had updated driver packs available for 1909, since I had simply copied the task sequence used for 1903.

A while ago I posted a blog with a script to download the latest driver packs from Dell using a web-scraping method, so I decided to take a similar approach for HP driver packs. HP publish a list of the driver packs available for various models and OS versions on the web in a tabular format, so I decided to try to convert that HTML table into data that could also be displayed in table format in PowerShell as well as being queryable, and the script below is the result.

	[CmdletBinding()]
	Param
	(
	[Parameter(Mandatory=$false)]
	[ValidateSet('64-bit','32-bit')]
	$Architecture = "64-bit"
	)
	# Load the HP driver pack web page
	If ($Architecture -eq "64-bit")
	{
	$URI = "https://ftp.hp.com/pub/caps-softpaq/cmit/HP_Driverpack_Matrix_x64.html"
	}
	If ($Architecture -eq "32-bit")
	{
	$URI = "https://ftp.hp.com/pub/caps-softpaq/cmit/HP_Driverpack_Matrix_x86.html"
	}
	$HTML = Invoke-WebRequest –Uri $URI –ErrorAction Stop
	# Scrape the table rows and headers for the datatable
	$TableRows = $HTML.AllElements | where {$_.tagName -eq "TR"-and $_.innerHTML -match "<P>"}
	$Headers = ($HTML.AllElements | where {$_.tagName -eq "TR" -and $_.innerHTML -match "Windows 10"})[0].innerHTML
	[string]$ColumnExpression = "<td[^>]*>(.*?)</td>"
	$HeaderMatches = [Regex]::Matches($Headers, $ColumnExpression, ([System.Text.RegularExpressions.RegexOptions]::Multiline, [System.Text.RegularExpressions.RegexOptions]::Singleline, [System.Text.RegularExpressions.RegexOptions]::IgnoreCase))
	# Load the headers as columns into a datatable
	$DataTable = New-Object System.Data.DataTable
	[void]$DataTable.Columns.Add("Model")
	foreach ($Match in ($HeaderMatches | Select –Skip 1))
	{
	[void]$DataTable.Columns.Add($Match.Value.Split('>')[1].Replace('</TD',''))
	}
	foreach ($Table in $TableRows)
	{
	[string]$ColumnExpression = "<td[^>]*>(.*?)</td>"
	$Matches = [Regex]::Matches($Table.innerHTML, $ColumnExpression, ([System.Text.RegularExpressions.RegexOptions]::Multiline, [System.Text.RegularExpressions.RegexOptions]::Singleline, [System.Text.RegularExpressions.RegexOptions]::IgnoreCase))
	$array = New-Object System.Collections.ArrayList
	# Process each regex match (table data entry)
	foreach ($Item in $Matches)
	{
	# Add the models
	If ($Item.Index -eq 0)
	{
	[array]$Models = ($Item.Value.Split('>') | where {$_ -match "/p"}).Replace("</P","")
	foreach ($Model in $Models)
	{
	[string]$ModelString = $ModelString + "$Model, "
	}
	$ModelString = $ModelString.TrimEnd(', ')
	[void]$array.Add($ModelString)
	Remove-Variable –Name ModelString –Force
	}
	# Add the driver pack url and version
	Else
	{
	If ($Item.Value -notmatch "<P>")
	{
	$Value = "–"
	}
	Else
	{
	$href = $Item.Value.Split() | Where {$_ -match "href"} | Where {$_ -match "exe"}
	$Link = $href.Split('>')[0].Replace('href="','').TrimEnd('"')
	$Version = ($Item.Value.Split('=') | where {$_ -match "Version"}).Replace('"','').TrimEnd(' href')
	$Value = "$Link ($Version)"
	}
	[void]$array.Add($Value)
	}
	}
	# Add an entry to the datatable
	If ($Architecture -eq '64-bit')
	{
	[void]$DataTable.Rows.Add($array[0],$array[1],$array[2],$array[3],$array[4],$array[5],$array[6],$array[7],$array[8],$array[9],$array[10],$array[11])
	}
	If ($Architecture -eq '32-bit')
	{
	[void]$DataTable.Rows.Add($array[0],$array[1],$array[2],$array[3],$array[4],$array[5],$array[6])
	}
	}
	Return $DataTable

This kind of data displays well in PowerShell’s gridview, like so:

Get-HPDriverPacks | Out-GridView 

In the first column you find the models and the next columns contain the driver pack version, release date and download URL for the various OS versions. You can then use the gridview’s native filtering capabilities to find something specific:

By default, the script will get the 64-bit driver packs, but you can also get 32-bit for Windows 7 etc (you’re not still using Windows 7 are you?!):

Get-HPDriverPacks -Architecture '32-bit'

I can also query the data within PowerShell directly, for example:

$DPs = Get-HPDriverPacks
$DPs | where {$_.Model -match "1040"} | Select Model,"Windows 10 64-bit, 1909"

To find out which models had driver packs for Windows 10 1909 that have been updated since the 1903 version, I did the following:

$DPs | 
    Where {$_."Windows 10 64-bit, 1909" -ne "-" -and $_."Windows 10 64-bit, 1909" -ne $_."Windows 10 64-bit, 1903"} | 
    Select Model,"Windows 10 64-bit, 1909" |
    Out-GridView

So those are the models whose driver packs I can update in the 1909 OSD task sequence.

You can also download the driver packs from this data too, eg:

$URL = ($DPs | where {$_.Model -match "1040 G6"} | Select -ExpandProperty "Windows 10 64-bit, 1909").Split()[0]
Invoke-WebRequest -Uri $URL -OutFile "C:\temp\$($url.Split('/') | Select -Last 1)"
