$pattern = '(..=)(?<Name>.*?)(?<!\\),(?<Path>.*)'

 

You can use this pattern to match the 'Name' of the OU and its parent 'Path' into named groups with those exact same names.

 

 
$a = "OU=TEST,DC=Halo,DC=net","OU=BATCH1,OU=TEST,DC=Halo,DC=net","OU=BATCH2,OU=TEST,DC=Halo,DC=net","OU=BATCH3,OU=TEST,DC=Halo,DC=net"


foreach ($b in $a) {


    $c = $b -match $pattern
