Powershell Parse Text File - parsing

Question

I am trying to parse this text file. It would have been easy to parse into a table like at the end, if there was a patter.
And I'm new to Powershell, so not sure how to tackle this problem.
Any help is appreciated.

RegEx can make fairly simple work of this. Import the file, join it together so that it's a single multiline string, then split it on lines that don't start with space. That gets you individual records. Then split those on new line characters, and parse each line depending on what's in it. Again, RegEx will help define each line is. This code will output an object for each section, with 4 properties, HardwareID, Name, Driver, and Files. The Files property is an array of files.
(Get-Content C:\Path\To\File.txt) -join "`r`n" -Split "(?m)^(?=\S)" |
Where{$_} |
ForEach{
Clear-Variable Files,Driver,Name,HardwareID
$Files = #()
$HardwareID = ($_ -split "`r`n")[0].trim()
Switch -regex ($_ -split "`r`n"){
"^\s+Name:" {$Name = ($_ -split ':',2)[-1].trim();Continue}
"^\s+.:\\" {$Files += $_.trim();continue}
"^\s+Driver" {$Driver = [RegEx]::Matches($_,"(?<=Driver installed from )(.+?)(?= \[)").value;continue}
}
[PSCustomObject]#{'HardwareID' = $HardwareID;'Name' = $Name; 'Driver' = $Driver; 'Files' = $Files}
}
So that will output something like:
HardwareID Name Driver Files
---------- ---- ------ -----
USB\ROOT_HUB20\4&361B340A&0 USB Root Hub C:\windows\INF\usbport.inf {C:\windows\system32\drivers\usbhub.sys, C:\windows\system32\drivers\usbd.sys}
ACPI\PNP0C09\1 {}
USB\ROOT_HUB20\4&361B340A&1 USB Root Hub C:\windows\INF\usbport.inf {C:\windows\system32\drivers\usbhub.sys, C:\windows\system32\drivers\usbd.sys}
ACPI\PNP0C09\2 {}
USB\ROOT_HUB20\4&361B340A&2 C:\windows\INF\cmbatt.inf {C:\windows\system32\DRIVERS\CmBatt.sys, C:\windows\system32\DRIVERS\battc.sys}
ACPI\PNP0C0A\2 Microsoft ACPI-Compliant Control Method Battery C:\windows\INF\cmbatt.inf {C:\windows\system32\DRIVERS\CmBatt.sys, C:\windows\system32\DRIVERS\battc.sys}
Edit: Ok, I'm going to assume that you didn't really try to modify what I had here since adding the Drivers to the list of other files should be really simple by changing $Driver = to $Files += just like the line above it to add that file to the array of files as well.Although, it looks like you want a line for each file, including the driver file, so maybe having an array for the files isn't best suited for you. What you could do is output an object for the driver file, and then an object for each of the supporting files, and you could get your version number for each on the fly as you make your objects. So you could replace the [PSCustomObject] line above with this:
[PSCustomObject]#{'HardwareID' = $HardwareID;'Name' = $Name; 'Files' = $Driver; 'FileVersion' = If(Test-Path $_.Trim()){[System.Diagnostics.FileVersionInfo]::GetVersionInfo($_.trim()).FileVersion}}
$Files | ForEach{ [PSCustomObject]#{'HardwareID' = $HardwareID;'Name' = $Name; 'Files' = $_; 'FileVersion' = If(Test-Path $_.Trim()){[System.Diagnostics.FileVersionInfo]::GetVersionInfo($_.trim()).FileVersion}Else{'File Not Found'}}}
This would output as:
HardwareID Name Files FileVersion
