Duration of specific task in task scheduler - powershell

Question

Taking inspiration on Get informations on Windows Scheduled Task duration (execution time)
we aim to filter on a set of tasks, instead of fetching all from task scheduler.
something of this sort:
$logName = 'Microsoft-Windows-TaskScheduler/Operational'
$xPathFilter = #'
*[
System[(EventID=200 or EventID=201)] and
EventData[
Data[#Name="TaskName"] = "001_task_A_nightly"
]
]
'#
Get-WinEvent -LogName $logName -FilterXPath $xPathFilter | Group-Object ActivityID | ForEach-Object {
$start = $_.Group |
Where-Object { $_.Id -eq 200 } |
Select-Object -Expand TimeCreated -First 1
$end = $_.Group |
Where-Object { $_.Id -eq 201 } |
Select-Object -Expand TimeCreated -First 1
New-Object -Type PSObject -Property #{
'TaskName' = $_.Group[0].Properties[0].Value
'Duration' = ($end - $start).TotalSeconds
Is there a way to adapt this one above?

Answer 1

Use the -FilterXPath parameter set instead, it'll allow you to granularly filter on the contents of the underlying event XML:
$logName = 'Microsoft-Windows-TaskScheduler/Operational'
$xPathFilter = #'
*[
System[(EventID=200 or EventID=201)] and
EventData[
Data[#Name="TaskName"] = "\MyTask" or
Data[#Name="TaskName"] = "\MyOtherTask" or
Data[#Name="TaskName"] = "\TaskFolder\SomeThirdTask"
]
]
'#
Get-WinEvent -LogName $logName -FilterXPath $xPathFilter |Group-Object ...
