Proposed contribution to the library: PAX (another XML library)
PAX - the "Pythonic API for XML" - is a XML-handling library. Like with DOM, you're supposed to first parse the whole stream into the internal representation, and then operate on it. What distinguishes PAX is that its implementation is python-oriented; you iterate trough child nodes via the normal ways (for, getitem, and in 2.2+, an iterator), the attributes are dictionary-based, etc. I used it to successfully reimplement TAL and PageTemplates (used in Zope). This reimplementation (AltPT) is quite stable and in production users in a few dozen servers around the world. PAX also includes a powerful python-oriented transform engine, which I used in Alt-TAL. The code has been tested on Python 2.1, 2.2 and recent CVS checkouts. It not only works, but transparently uses recent interesting features when available - notably, enumerate(). Most of the code is in public domain, and of course I make no objections to switching to PSL. In fact the package was designed all along with the intention of offering it to the standard library (and I like to think that this led me to cleaner design and a readable implementation). It is in active maintenence; if not much development happened in the last few months, it's because it reached some maturity. In fact I just released 1.0alpha1 before sending this mail (15k tar.bz2) PAX has a small site at my very-slow (due to bad connectivity) Zope server at http://python.laranja.org/pax/ - this site, btw, runs on AltPT. The releases can be found there, and the cvs is (for hystorical reasons) at :pserver:anonymous@cvs.sf.net:/cvsroot/flyingcircus module miscfiles/python/pax (because it was originally developed as I needed an XML library for my "flyingcircus" pda project). Should I write a PEP? Or a patch (silly, it would be a quite big patch)?

I think a library PEP would be needed. However, I would encourage you first to collect a user community for this code, and consider inclusion in the Python core only after a few years. One vehicle for potentially wider distribution of your code would be inclusion into PyXML, which I would help to perform if desired. Regards, Martin

how is this different from ElementTrees or all the other light-weight DOM variants out there? how much memory does it use, compared to minidom and the pyxml tools? how fast is it (compared to the same tools? compared to more optimized tools such as libxml and henry spencer's stuff?) (I think the right approach would be to add it to the xml-sig distribution first, and move it into the core only when you have more than a dozen users...) </F>

This seems reasonable. Perhaps I was over-hasted by the threat of 2.3a ;-) I will subscribe to the XML-sig asap.
