How to remove duplicate tags from supplementalCategories?

[stephanie]

Hello Phil,

You already helped me a lot with exiftool. Thank You very much for this.

Now I have a new question about removing duplicate tags:

I have supplementalCategories tags as the following:

"Nature, Trees, Wood, Plants, Pine Trees"
"Trees, Plants, Leaf Trees, Trees"
"Plants, Trees, Nature, Trees, Wood"
"Leaf Trees, Trees, Plants, Trees, Nature, Wood"
And so on...

I want to delete all duplicates of the tag "Trees". But tags containing the word "Trees" (e.g. "Leaf Trees") shall not be deleted.

Which is the correct code to realize this?

Many greetings from

Stephanie
