Tokens, renaming - I do not get it

Problem:

I get my banking statements via online banking as a PDF.
Inside the PDF there is a number, increased each time I download the newest statement.
I use content matches "Nr. [123]" and become a green match.

Now I want to rename it to:

Banking 2019-[123].pdf

So, I've to use a token to take over the found number for renaming, right?
But if I use a token, name it "Nr." search for "Nr. [123]" my PDF file will renamed to:

Banking 2019-Nr..pdf

I tried different things but it seems I do not understand how tokens work. :-(

Can someone please tell me step-by-step how I've to configure Hazel so that I can insert a matched Text, in my case a two digit number later on renaming.
Thanks.

Can you post screenshots of your rule? You can't upload files here directly so I suggest using a third party image hosting service, like Dropbox or imgur.com.

This is the part of the PDF. Number is increasing, only the part (XX) is important for me "Nr. XX/1"

Here I use a Token so far as I understand it... I tried different placeholders.

But the result is wrong:

I want that number from my Pdfs pasted into the renamed name of the PDF file.

Try using Hazel's preview function and see what Hazel captures in the custom attribute. Also, I'm not sure if you want the Nr in the renamed file or not. If you don't, you want it outside of the custom attribute.

Hazel capture it correctly. My question is, how can I use the recognized number to the renamed name?

E.g.: Inside the PDF is "NR. 23/1" so the renamed file should be renamed to "Kontoauszug 2019-23"; "Nr. 24/1" is recognized, the the name should be "Kontoauszug 2019-24" and so on.

In that case, check the logs. Search for a specific file that isn't being named correctly and post the relevant excerpts.

The Hazel tokens are useful for really basic operations, but for anything more complex I always end up resorting to a bash script

(easier to debug, run manually etc).

Have you considered doing that?

I don't know how complex it would be to do my renaming wish with a bash script. I've used Automator before, but find Hazel more powerful and hoped that with its Tokens I could rename my PDFs with parts I found inside them. But I've really problems to understand how this is working. I didn't find examples/tutorials I could re-enact. Watched some YT-Videos, there it works perfect, but without explaining it. So I need a step-by-step instruction.

The dime has not fallen to me yet. :roll:

Again, can you post the logs showing the rename operation?
