It was just for fun. Both SAX APIs are sorta nebulous as it is to someone like me who's been so used to an abundance of tutorials on the tools I regularly use. Ox's SAX API was better, though.

I had just wanted to speed up my XML parser and stumbled upon a Nokogiri vs Ox benchmark (http://www.ohler.com/dev/xml_with_ruby/xml_with_ruby.html). So I tried Ox.

Here's my effort to benchmark Nokogiri vs Ox, DOM vs SAX parsing on an 80mb XML file with 38k nodes: https://gist.github.com/3977120

    Ox DOM: 6 seconds (550mb)
    Ox SAX: 6 seconds (12mb)
    Nokogiri DOM: 13 seconds (900mb)
    Nokogiri SAX: 24 seconds (11.8mb)

I'm no benchmarking wizard, though.
