This module contains a parser to parse PICA+ XML. Up to now PICA+ XML is not fully standarized yet so this parser may slightly change in the future.
Creates a new Parser. See PICA::Parser for a description of parameters to define handlers (Field and Record).
Parses data from a string, array reference or function. Data from arrays and functions will be read and buffered before parsing. Do not directly call this method without a PICA::XMLParser object that was created with new().
Parses data from a file or filehandle.
Get the number of read records so far.
Get the number of empty records that have been read so far. By default empty records are not passed to the record handler but counted.
Do not directly call this methods.
Called at the beginning.
Called at the end. Does nothing so far.
Called for each start tag.
Called for each end tag.
Called for character data.
Get the handlers (init_handler, final_handler, start_handler, end_handler, char_handler).
Get the current position (file name and line number).
XML namespaces are not supported yet. When XML errors occur, there should be better error messages that point to a give file and line. Return values of collections are not supported yet.
