If a property begins with a '#' character, this kills Show-object

[1RedOne]

Found a weird one.

[xml]$xml = wget https://patchmypc.net/category/SCUPCatalogChanges/feed Show-Object $xml

This object has a property which is named '#comments', and Show-object runs into the following error when trying to parse this:

Invoke-Expression : At line:1 char:20

• $resultObject = $a.#comment

•                ~
  

  Missing property name after reference operator. At C:\Program Files\WindowsPowerShell\Modules\PowerShellCookbook\1.3.3\PowerShellCookbook.psm1:7648 char:9

•     Invoke-Expression "`$resultObject = $nodePath"
  

•     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The variable '$resultObject' cannot be retrieved because it has not been set. At C:\Program Files\WindowsPowerShell\Modules\PowerShellCookbook\1.3.3\PowerShellCookbook.psm1:7651 char:36

The code in question

## Walk through its parents, creating the virtual
        ## PowerShell syntax to access this property.
        $nodePath = GetPathForNode $selectedNode 

        ## Now, invoke that PowerShell syntax to retrieve
        ## the value of the property.
        Invoke-Expression "`$resultObject = $nodePath"

        ## And populate the node with the result object.
        PopulateNode $selectedNode $resultObject
