Created attachment 120184 [details] MARC authority record with two 151$x Hi all, I think this is a bug, if someone could confirm, I would appreciate it! In MARC modification templates, we have the option of choosing to modify the first or every field specified. But when trying to delete only the first occurrence of a subfield, it deletes every subfield anyway. To test: 1) Create an authority record with two 151$x, one containing [BLANK] and the other containing real information (I've attached my authority record if you want to simply import it) 2) Go to Tools > MARC modification templates 3) Create a new template 4) Add the following action Delete 1st field(s) 151 x if field 151 x matches [BLANK] 5) Go to Tools > Batch record modification 6) Fill in the form Record type: Authorities Enter a list of record numbers: enter the authid of your authority record Modify record using the following template: Template created previously 7) Click Continue 8) Click "Show MARC" Both 151$x are deleted, rather than just the first one
I did some more experimenting Delete 1st 151 x if 151 x matches [BLANK] Expected: only the first $x will be deleted Result: both $x are deleted Delete Every 151 x if 151 x matches [BLANK] Expected: both $x will be deleted Result: both $x are deleted Move 1st 151 x to 151 g RegEx \[BLANK\] / gggg / if 151 x matches [BLANK] Expected: one $x remaining and one $g with gggg Result: no $x, one $g with gggg Move Every 151 x to 151 g RegEx \[BLANK\] / gggg / if 151 x matches [BLANK] Expected: one $g with gggg (? not sure about this? Should the $xRecensement still be there because it doesn't match the RegEx?) Result: one $g with gggg Copy 1st 151 x to 151 g RegEx \[BLANK\] / gggg / if 151 x matches [BLANK] Expected: two $x remaining, one new $g with gggg Result: two $x remaining, one new $g with gggg Copy Every 151 x to 151 g RegEx \[BLANK\] / gggg / if 151 x matches [BLANK] Expected: two $x remaining, one new $g with gggg (I think? again, I'm not sure if the RegEx has any effect on which $x is copied) Result: two $x remaining, one new $g with gggg Copy and replace 1st 151 x to 151 g RegEx \[BLANK\] / gggg / if 151 x matches [BLANK] Expected: two $x and one $g with gggg Result: two $x and one $g with gggg Copy and replace Every 151 x to 151 g RegEx \[BLANK\] / gggg / if 151 x matches [BLANK] Expected: two $x and one $g with gggg Result: two $x and one $g with gggg
