I am trying to create a powershell scripts for Remote Desktop Connection Manager using the active directory module.

My first thought was get a list of computers in AD and parse them out into XML format similar to the OU structure that is in AD. I have no problem with that, the below code will work just but not how I wanted.

EG # here is a the array $OUs

Americas/Canada/Canada Computers/Desktops
Americas/Canada/Canada Computers/Laptops
Americas/Canada/Canada Computers/Virtual Computers
Americas/USA/USA Computers/Laptops
Computers
Disabled Accounts
Domain Controllers
EMEA/UK/UK Computers/Desktops
EMEA/UK/UK Computers/Laptops
Outside Sales and Service/Laptops
Servers

I wanted to have the basic XML structured like this

Americas
    Canada
        Canada Computers
            Desktops
            Laptops
            Virtual Computers
    USA
        USA Computers
            Laptops
Computers
Disabled Accounts
Domain Controllers
EMEA
    UK
        UK Computers
            Desktops
            Laptops
Outside Sales and Service
    Laptops
Servers

However if you run the below it does not nest the next string in the array it only restarts the from the beginning and duplicating

Americas
    Canada
        Canada Computers
            Desktops
Americas
    Canada
        Canada Computers
            Laptops
Americas
    Canada
        Canada Computers
            Virtual Computers
Americas
    USA
        USA Computers
            Laptops
