Catmandu::Validator::MARC(3pm)

Usage

In Perl code:

    use Catmandu::Validator::MARC;
    Catmandu::Validator::MARC;
    use DDP;
        
    # load default MARC schema
    my $validator = Catmandu::Validator::MARC->new();
    
    # ... or load custom MARC schema
    my $validator = Catmandu::Validator::MARC->new( schema => 'schema.json' );
    my $importer = Catmandu::Importer::MARC->new(
        file => 't/camel.mrc',
        type => "ISO"
    );
    $importer->each( sub {
        my $record = shift;
        unless($validator->validate($record)){
            p $_ for @{$validator->last_errors()};
        }
    });

In Catmandu Fix language:

    # reject all items not conforming to the default MARC schema
    select valid(., MARC)
    # reject all items not conforming to a custom MARC schema
    select valid(., MARC, schema: 'schema.json')

Overview

See also Catmandu::Fix::validate, and Catmandu::Fix::Condition::valid for usage of validators in Catmandu Fix language.
