NAME
PICA::SRUSearchParser - Parse a SRU response in XML and extract PICA+ records.
METHODS
new
Creates a new Parser. See PICA::Parser for a description of parameters to define handlers (Field and Record).
parseResponse
Parse an SRU SearchRetrieve Response given as an XML string.
counter
Get the number of read records so far.
empty
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.
size
Get the total number of records in the SRU result set. The result set may be split into several chunks.
resultSetId
Get the SRU resultSetId.
PRIVATE HANDLERS
Do not directly call this methods!
_start_handler
SAX handler for XML start tag. On PICA+ records this calls the start handler of PICA::XMLParser, outside of records it parses the SRU response.
_end_handler
SAX handler for XML end tag. On PICA+ records this calls the end handler of PICA::XMLParser.
_char_handler
SAX handler for XML character data. On PICA+ records this calls the character data handler of PICA::XMLParser.
TODO
There seems to be a memory leak in the new() method, try while(1) { my $parser = PICA::SRUSearchParser->new(); }
A method to get the parameters in the header (numberOfRecords, resultSetId...) is needed to get the number of records before actually parsing the result.
Following requests of next records it not implemented yet.
There is no check whether the SRU server supports pica format.
Better error handling would be nice to skip invalid records but parse the rest.
We need test cases.
