constructs a new XML::SemanticCompare::SAX reference. parameters (all optional) include:

parser - the parser to use.

This subroutine allows you to select the SAX implementation that is used by this SAX parser. Argument is a scalar string.

The following options are available, but are not limited to:

XML::LibXML - not actually a SAX engine, but emits SAX events

XML::LibXML::SAX - a SAX parser provided by XML::LibXML

XML::LibXML::SAX::Parser - another SAX parser provided by XML::LibXML; the one used by default. Not sure how different it is from XML::LibXML::SAX

XML::SAX::PurePerl - pure perl implementation; not very efficient.
