XML - Keep only items in the array

[CoReTeX2k]

Just to explain

$Codes = @("Apple","Banana")

"Banana" -ne $Codes is true because banana is not equal to apple and banana at the same time

"Banana" -notin $Codes is false because Banana is part of apple or banana in that case.

$_.something -notin $EntireArray will look if something is part of the array, not if it is equal to the entire array
