How can I remove the "base" part of the path?

I need to recreate a series of folders in a source directory in another environment. The source folder looks like this:

C:\temp\stuff\folder01\
C:\temp\stuff\folder02\
C:\temp\stuff\folder03\
C:\temp\stuff\folder02\dog
C:\temp\stuff\folder02\cat

I need to remove the base part of the path C:\temp\stuff- and get the rest of the path to join with the target base folder in order to create the folder structure elsewhere.

I have the following script. The problem seems to be with the variable $DIR. $DIRThe expected "current path minus base path" is never assigned.

The variable was $tmpassigned a name close to the expected folder name. It contains the folder name minus vowels, is split on multiple lines, and contains a bunch of leading spaces. For example, a folder named folder01as follows:

f
ld
r01

Here is the PowerShell script:

$SOURCES_PATH = "C:\temp\stuff"
$DESTINATION_PATH = "/output001"

Get-ChildItem "$SOURCES_PATH" -Recurse -Directory |
Foreach-Object {

    $tmp = $_.FullName.split("$SOURCES_PATH/")

    $DIR = $_.FullName.split("$SOURCES_PATH/")[1]

    $destination = "$DESTINATION_PATH/$DIR"

    *** code omitted ***
}

I suspect $DIRit seems to be unassigned because the [1] element is a space, but I don't know why there is a space and what happened to the folder name.

What's going on and how can I fix it?
