NAME

PICA::Parser::Base - abstract base class of PICA parsers

SYNOPSIS

    use PICA::Parser::Plain;
    my $parser = PICA::Parser::Plain->new( $filename );

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

    use PICA::Parser::Plus;
    my $parser = PICA::Parser::Plus->new( $filename, bless => 1 );
    ... # records will be instances of PICA::Data

    use PICA::Parser::XML;
    my $parser = PICA::Parser::XML->new( $filename, start => 1 );
    ...

DESCRIPTION

This abstract base class of PICA+ parsers should not be instantiated directly. Use one of the following subclasses instead:

PICA::Parser::Plain

PICA::Parser::Plus

PICA::Parser::Binary

PICA::Parser::XML

PICA::Parser::PPXML

PICA::Parser::JSON

CONFIGURATION

blessed

Return records as instances of PICA::Data (disabled by default).

strict

By default faulty fields in records are skipped with warnings. You can make them fatal by setting the strict parameter to 1.

annotated

By default some parsers also support annotated PICA. Set to true to enforce field annotations or to false to forbid them.

METHODS

new( [ $input | fh => $input ] [ %options ] )

Initialize parser to read from a given file, handle (e.g. IO::Handle), or reference to a Unicode string. PICA::Parser::XML also detects plain XML strings.

next

Reads the next PICA+ record. Returns a (optionally blessed) hash with keys _id and record, as defined in PICA::Data.

SEE ALSO

See Catmandu::Importer::PICA for usage of this module in Catmandu.

Alternative PICA parsers had been implemented as PICA::PlainParser and PICA::XMLParser and included in the release of PICA::Record (DEPRECATED).
