SAX is stands for Simple API for XML.It is a lexical and event-driven interface.Implementation of SAX is fast and efficient but we can\'t extract information from XML at random.It is good for use when some types of information ewe handle in same way always without knowing that where it execute in document.
How to use SAX in XML:
# Use to get a list of known parsers
my $parsers = XML::SAX->parsers();
# Use to add/update a parser
# Use to remove parser
# Use to save parsers
