Problem w/Register-ScheduledTask in Powershell v5.1-CodePudding

Ok, I have the following code which retrieves a file from my main machine makes an adjustment and then creates a Scheduled Task on my test machine. The program is run from the test machine. This works just as it should.

$SRCXMLPath = "\\Dellxps8920\BEKDocs-DellXPS8920\TaskSchedulerExports\Tasks"
$DestXMLPath = "G:\BEKDocs\TaskSchedulerExports\Standard"
$XMLFile = "Backup Report.xml"

$GCArgs = @{Path = 
             $(Join-Path -Path $SRCXMLPath -ChildPath $XMLFile)}

[xml]$xml = Get-Content @GCArgs

$xml.Task.RegistrationInfo.Author #Has no effect on running!

$xml.Task.Principals.Principal.UserId

<# ---------------------------------------------------- 
  | Note: You can use either the text description of   |
  |       the account or the Registry designation.     |
   ---------------------------------------------------- 
#>

$xml.Task.Principals.Principal.UserId = 
  'DellXPS8700\Bruce'

#  "S-1-5-21-1944453205-1635450679-2182824496-1001"

$xml.save()

& schtasks.exe /create /tn "Backup Report" /xml "$(Join-Path -Path $DestXMLPath -ChildPath $XMLFile)"

However, I'm trying to convert it to Full PowerShell via Register-ScheduledTask cmdlet to eliminate the call to schtasks.exe. Using the following test code I consistently get the displayed error.

[xml]$Task = Get-Content "G:\BEKDocs\TaskSchedulerExports\Standard\Backup Report.xml"
$RTArgs = @{TaskName = "Backup Report"
            TaskPath = "\"
            XML      = $Task
            Force    = $True}

Register-ScheduledTask @RTArgs

Error Message:

Register-ScheduledTask @RTArgs
Register-ScheduledTask : The task XML is malformed.
(1,2)::ERROR: incorrect document syntax

  Register-ScheduledTask @RTArgs

   ..S_ScheduledTask) [Register-ScheduledTask], CimException

Anyone have any Ideas?

Please Note: the .xml file works perfectly with the code at the top of the post or if it is imported manually inside TaskSheceuler.

CodePudding user response：

You're reading the XML file as an XML object, but the cmdlet expects a string object.

Register-ScheduledTask
        [-Force]
        [[-Password] <String>]
        [[-User] <String>]
        [-TaskName] <String>
        [[-TaskPath] <String>]
        [-Xml] <String>
        [-CimSession <CimSession[]>]
        [-ThrottleLimit <Int32>]
        [-AsJob]
        [<CommonParameters>]

Change the line to read the file in as just one string and you should be all set.

$Task = Get-Content "G:\BEKDocs\TaskSchedulerExports\Standard\Backup Report.xml" -raw
