Hi Klas, This could be wrong, but since you want to retain 887s with $m subfields that are either A) empty or B) one of your branch codes, could you just add the regex for an empty string "^$" to your existing pattern? So Delete field 887 if 887$m does not match RegEx m/\Gull|Hjo|Hova|Kabo|Mari|Sksb|Tida|Tikf|Tore|^$/ I'm not sure if that works, basically it relies on Koha's MARC parsing treating a missing subfield as an empty string.

Our Union catalogue sends us hundreds of redundant Marcfields 841, 852, 887 relating to local information for all participating libraries. There are 860 libraries in the union catalogue, so we are really drowning in unneeded info
I'm trying to set up a Marc-modification template to delete 841/852/887-fields that are for libraries outside our consortium of nine libraries
The 841 and 852-fields looks like this: 852 ? - LOCATION b Sublocation or collection E H Classification part Topo Västergötl 5 Librarycode E
852 ? - LOCATION B Sublocation or collection Tida H Classification part fol 5 Librarycode Tida
I managed to delete unwanted 841/852 fields with this template: Delete field 852 if 852$5 does not match RegEx m/\Gull|Hjo|Hova|Kabo|Mari|Sksb|Tida|Tikf|Tore/
The real challenge comes with field 887!
The first instance doesn't contain a librarycode - but should be kept The following instances contains a library code, and should be deleted unless they contain any of our librarycodes
Any ideas? I realize this is quite a challenge
