The API is exactly the same as any other Perl SAX2 parser. See
XML::SAX::Intro for details.
Aside from the regular parsing methods, you can access the
DOM tree traverser directly, using the generate() method:
my $parser = XML::GDOME::SAX::Parser->new(...);
This is useful for serializing DOM trees, for example that
you might have done prior processing on, or that you have
as a result of XSLT processing.
