If you want a very fast validating XML parser, RXP would also be a good choice -- AFAIK, the RXP folks would allow us to ship RXP under a different license than GPL which is then bound to Python.
RXP would indeed be a choice. Of course, integrating it is much harder; you'd have to write the C module first, plus documentation, plus a SAX driver, plus test cases. I'm not sure how much code you can inherit from PyLTXML.
On performance: Please have a look at
http://www.xml.com/lpt/a/Benchmark/exec.html
which suggests that expat still has a speed advantage over rxp (assuming that the measurements where done carefully, i.e. disabling validation in RXP).
How would libxml fit into this picture ? http://xmlsoft.org/ libxml is written in C as well and under the LGPL. There's also Apache's Xerces which is written in a portable subset of C++ (is probably to big though to be intergated into Python): http://xml.apache.org/xerces-c/ -- Marc-Andre Lemburg CEO eGenix.com Software GmbH ______________________________________________________________________ Consulting & Company: http://www.egenix.com/ Python Software: http://www.lemburg.com/python/
