Thank you for all the help I've ever gotten here.

Scenario: Parsing XMLs Recursively into a neat CSV

I have managed to parse one XML into a CSV:

$xmlFile = [xml](get-content "OneDrive Reporting Task-S-1-5-21-xxxxxxxx-xxxxxxxx-683614252-544134134")
$Date = $xmlFile.ChildNodes.RegistrationInfo.Date
$Author = $xmlFile.ChildNodes.RegistrationInfo.Author
$Description = $xmlFile.ChildNodes.RegistrationInfo.Description
$URI = $xmlFile.ChildNodes.RegistrationInfo.URI
$Principals = $xmlFile.ChildNodes.Principals.Principal.UserId
$LogonType = $xmlFile.ChildNodes.Principals.Principal.LogonType
$Enabled = $xmlFile.ChildNodes.Triggers.CalendarTrigger.Enabled
$Action = $xmlFile.ChildNodes.Actions.Exec.Command
$Arguments = $xmlFile.ChildNodes.Actions.Exec.Arguments

$xmlFile.ChildNodes[1] | 
ForEach-Object{
         [PSCustomObject]@{
             Registration_Date = $Date
             Author = $Author
             Description = $Description
             URI = $URI
             Principals_UserContext = $Principals
             LogonType = $LogonType
             Enabled = $Enabled
             Action = $Action
             Arguments = $Arguments
         }
     } | Export-Csv .\01Parsed_Tasks_XML.csv -NoTypeInformation

The idea is to look for XMLs recursively in a Folder, and do all the above and keep appending the data. I'll keep trying but in the meanwhile, would appreciate some help too.
