NAME
PICA::Data - PICA record processing
FUNCTIONS
pica_parser( $type [, @options] )
Create a PICA parsers object. Case of the type is ignored and additional parameters are passed to the parser's constructor.
- PICA::Parser::XML
-
Type
xmlorpicaxmlfor PICA+ in XML - PICA::Parser::Plus
-
Type
plusorpicaplusfor normalizes PICA+ - PICA::Parser::Plain
-

plainfor plain, human-readable PICA+
pica_writer( $type [, @options] )
Create a PICA writer object in the same way as pica_parser with one of
pica_values( $record, $path )
Extract a list of subfield values from a PICA record based on a PICA path expression.
pica_value( $record, $path )
Same as pica_values but only returns the first value. Can also be called as value on a blessed PICA::Data record.
pica_fields( $record, $path )
Returns a PICA record limited to fields specified in a PICA path expression. Always returns an array reference. Can also be called as fields on a blessed PICA::Data record.
pica_holdings( $record )
Returns a list (as array reference) of local holding records (level 1 and 2), where the _id of each record contains the ILN (subfield 101@a).
pica_items( $record )
Returns a list (as array reference) of item records (level 1), where the _id of each record contains the EPN (subfield 203@/**0).
pica_items( $record )
pica_path( $path )
Equivalent to PICA::Path->new($path).
OBJECT ORIENTED INTERFACE
All pica_... function that expect a record as first argument can also be called as method on a blessed PICA::Data record by stripping the pica_... prefix:
bless $record, 'PICA::Data';
$record->values($path);
$record->items;
