[librecat-dev] marc_match does not like 8806?

[Patrick Hochstenbach]

Hi

I’m sorry this is such a pain. This fix should do the trick:

do marc_each()
if marc_match(8806,'100')
  set_field(zzz,true)
end

if marc_match(1006,'880')
  set_field(yyy,true)
end
end

retain(_id,yyy,zzz)

which will result in:

% catmandu convert MARC to YAML --fix my.fix < author.mrc
---
_id: in00005597484
...
---
_id: in00005597483
yyy: 'true'
zzz: 'true'
...

It is safer when you need to reason over MARC fields that are repeated (such as the 880) field to use the `do marc_each() …. end` construct. This will process a MARC record line by line.

Hello,

I am lost :(
I am now fighting my way through a mixed pile of single- and multi-script MARC-records.
This was meant as a simple check if there exists a non-Latn version of – for example - the author field (MARC 100) - here tested with “convert to YAML” to see if it is working at all:
if marc_match(8806,'100')
set_field(zzz,true)
end
But it doesn’t work.
But this does:
if marc_match(1006,'880')
set_field(yyy,true)
end
What am I missing?
I attach a 2 record sample (one with a non-linked 100, one with 100$6880). The second one should return both zzz:true, yyy:true but only returns yyy:true.

(just starting from the 100 field is not an option, because sometimes the $6880 is missing in the records I have, while the 880ies seem all to have $6 references)

Best,
Martina
