PowerShell XML PSCustomObject powershell

I tried several approaches but none seem to work. I keep running into I've been banging my head against this for hours. I'm working with an scenario with PowerShell 7.3 where I'm trying to convert XML data into custom PowerShell objects. My XML file has a complex structure, and while I can parse it into a PSObject, I encounter an behavior when I try to select specific properties. Here’s a snippet of what I’m doing: ```powershell [xml]$xmlData = Get-Content 'data.xml' $customObjects = $xmlData.Document.Element | ForEach-Object { [PSCustomObject]@{ Name = $_.Name Value = $_.Value NestedData = $_.NestedElement } } $result = $customObjects | Select-Object Name, Value, NestedData ``` However, when I run this script, I get the following behavior: ``` Select-Object : want to bind argument to parameter 'Property' because it is null. ``` I've verified that the `$_` variable inside the `ForEach-Object` loop contains the expected elements. I also tried using `Select-Object` directly inside the loop, but that didn't work either. It seems like the `NestedData` property, which is an element that can contain multiple child nodes, might be causing the scenario. I even attempted to flatten this property by converting it to an array, but I still run into problems. I've also ensured that the XML structure is consistent and that all properties I’m trying to access exist. Any guidance on how to resolve this or best practices for handling nested XML structures in PowerShell would be greatly appreciated. For context: I'm using Powershell on Linux. What's the best practice here? This issue appeared after updating to Powershell 3.10. Any advice would be much appreciated.
