Bio::SearchIO::XML::BlastHandler - XML Handler for NCBI Blast XML parsing.
# This is not to be used directly.
This is the XML handler for BLAST XML parsing. Currently it passes elements off to the event handler, which is ultimately responsible for Bio::Search object generation.
This was recently split off from the original code for Bio::SearchIO::blastxml primarily for maintenance purposes.
In addition to parts of the Bio:: hierarchy, this module uses:
which comes with the XML::SAX distribution.
