Have documents moved based on content within different file

I want my eBooks sorted. I have a few thousand of these and no overview which to keep and which to delete. All of these are in the epub-format and are named "last name, first name_book title.epub".

For this I'm trying to get Hazel to look through a list within either a numbers file or a pages file (whatever works better) in which I keep names of authors which I don't like. Based on the content of this file I want to look for matches with the existing file names of the eBooks. If there's a match Hazel should move the file to the trash. This way, if I add to the collection by copying from a friends drive all uninteresting literature willl get deleted automatically.

Since there are just too many books I can't simply make a rule for each author because then I would have to create at least a few hundred rules...

Any ideas?

You'd probably need a script to read in this file and accept/reject accordingly. I would recommend against use Numbers or Pages since their file formats are proprietary and not easily readable. A plain text file is probably best.

That's what I thought. I can easily use a plain text document but have no clue about apple script. Are there some ideas how to edit the script accordingly?

You can edit the file using TextEdit. As for the script itself, that's beyond the support I can give but maybe someone else here could help out.
