IE just XML::LibXML (Without the sax) which we now know is a lot faster :) Galen's tests essentially do the same thing, except with passing it through MARC::File::XML
Comparisons are odious. DOM uses an underlying SAX parser to load any XML document in memory. DOM is not as SAX parser as itself. Galen tests, as I understand them, show that current MARC::File::XML parser, which include a specif SAX event handler, is slower than loading directly a DOM document. It contradicts the theory. The explanation is, as stated by Galen, that Perl SAX parser implementation is not good... My tests use XML::Simple and so load the whole MARCXML document in memory before rendering it into a MARC::Record object. It gives a picture of the difference between parsing MARCXML in pure Perl vs using an external SAX parser. -- Frédéric
