rename multiple sub layers at once

[Mizanur R.22632073hlcl]

Hello,

i used this code for replacing names in layers from github (adobe-illustrator-layer-renamer/Rename Layers.jsx at master · seblavoie/adobe-illustrator-layer-rena... )

it works fine but it just renames top level layers. Can somebody explain how can I rename multiple sub layers at once.

thanks in advance
