I am writing a filtering HTTP proxy (the site is http://xuproxy.sourceforge.net/). I want it to be compatible with Proxomitron (http://proxomitron.info/) filters. I need a regular expression parser that allows patterns to call functions (or more likely, class methods), to implement "matching commands" (look at the Proxmitron documentation to see what I mean). Does anyone know if such a library exists for Python, or do I have to write my own parser? -- http://mail.python.org/mailman/listinfo/python-list
