I found the SAX parser of XML::LibXML rather slow compared to parsing 
whole document trees and using XPath. That's primarily because there is 
a lot of back-and-forth between Perl and C code.

Also note that when using XML::LibXML, there's a third option: a pull 
parser based on libxml2's xmlTextReader. See

     https://metacpan.org/module/XML::LibXML::Reader

It's faster than the SAX parser and like the SAX parser, it's suitable 
for large documents.
