Aaron was kind enough to help me out with the RapidXml test. RapidXml is written in highly-tuned C++, and does give Tango a run for the money. I am really glad we are starting to add some non-Java alternatives, so we can see what native code can do. Without further ado, the code is bench_rapidxml.cpp, which was compiled via:
g++ bench_rapidxml.cpp -O2 -o bencn

I looked at rapidXML and decided not to take it seriously because it doesn’t do anything, no name space, no attribute unquiness checking, no UTF-8 support, basicly does nothing. so if it doesn’t do anything, the performance doens’t matter, but it is not useful for any serious use…

What is considered serious use? Many of the parsers I tested are not XML compliant, including VTD-XML. But they all serve some purpose to someone.

You might want to try adding -DNDEBUG to that command line, it may speed things up a bit.
