NAME

MARC::Parser::RAW - Parser for ISO 2709 encoded MARC records

SYNOPSIS

    use MARC::Parser::RAW;

    my $parser = MARC::Parser::RAW->new( $file );

    while ( my $record = $parser->next() ) {
        # do something        
    }

DESCRIPTION

MARC::Parser::RAW is a lightweight, fault tolerant parser for ISO 2709 encoded MARC records. Tags, indicators and subfield codes are not validated against the MARC standard. Record length from leader and field lengths from the directory are ignored. Records with a faulty structure will be skipped with a warning. The resulting data structure is optimized for usage with the Catmandu data tool kit.

MARC::Parser::RAW expects UTF-8 encoded files as input. Otherwise provide a filehande with a specified I/O layer or specify encoding.

MARC

The MARC record is parsed into an ARRAY of ARRAYs:

    $record = [
            [ 'LDR', undef, undef, '_', '00661nam  22002538a 4500' ],
            [ '001', undef, undef, '_', 'fol05865967 ' ],
            ...
            [   '245', '1', '0', 'a', 'Programming Perl /',
                'c', 'Larry Wall, Tom Christiansen & Jon Orwant.'
            ],
            ...
        ];

METHODS
