Hi,
How do you sort record's MARC fields using the Fix language?
Since I am adding new fields they are now in a "random" order. I would like
to sort them in the order similar to what they were originally in ("FMT",
"LDR" and then the numeric fields in the increasing order).
---
Also, is there a fix similar to retain() but for MARC fields?
Currently I am filtering MARC fields (based on a whitelist) like this:
# Keep only the fields that are needed
set_array(ok_fields, FMT, LDR,
008, 040, 041, 075, 100,
240, 245, 246, 260,
377, 380, 388, 400, 490,
600, 630, 650, 670, 677,
700, 720, 908, 910)
do marc_each()
copy_field(record.0.0, fld_type)
unless in(fld_type, ok_fields)
remove_field(record)
end
remove_field(fld_type) # is this needed?
end
remove_field(ok_fields)
Thanks,
Uldis
