WikiXRay parser research
Cut & paste the following code in a text file, and save it as dump_sax_research.py. Don't forget to give your file executable privileges.
It uses a tweak to speed up the parsing process, consisting on filtering the text events so that the characters method is called only when the complete text block has been buffered. You can see further details of this recipe in the Python CookBook (though I retrieved mine from the second edition of the printed version of the Python Cookbook, by O'Reilly; obviously, they explicitly give you permission to use the code for this purpose).
