Hi collective wisdom, I'm running into a MARC modification template problem and I can't tell if I'm missing something or there's a bug/limitation. I know I could accomplish these edits with MARCEdit or a script, but I was hoping to use Koha's tools.
I have a record with two 856 fields with links, I want to apply our proxy server prefix to one link but not the other. That seems to be impossible; Koha clobbers the second link with a copy of the first. Here's a minimal example. Record 245 _ _ ‡aExample 856 4 0 ‡uhttps://example.com‡yLink to proxy 856 4 0 ‡uhttps://www.cca.edu‡yLink to retain MARC modification Copy and replace 1st field(s) 856 u to field 856 u Regex ✅ s/^http/ https://proxy.cca.edu/url?=http/ If field 856 u matches m/https://example.com/ Regex ✅ Output record 245 _aExample 856 40 _uhttps://proxy.cca.edu/url?=https://example.com _yLink to proxy 856 40 _uhttps://proxy.cca.edu/url?=https://example.com _yLink to retain This happens whether I set the modification template to use the "1st" or "every" 856 field. I don't understand why the second 856 is touched at all, since it does not meet the "if" condition, much less why instead of receiving its own link proxied it gets the first 856 URL proxied. Based on a few tests, it also seems like the "1st" field with respect to modification actions is not always the one that's visually first when I edit a record. I tried a set of three actions which 1) copied the first field to another, unused field, 2) modified it there, and then 3) copied it back, but Koha copied the second field instead.
