Python is faster and easier for a Python engine to parse. It's probably easier and faster to (correctly) parse XML than JSON for an Python engine, and vice versa. In the end, as a long-certified XML doc head I think XML is just not suited to the bit jewelry of highly structured data. It's more suited to the sloppy exigencies of prose. I think all these rumblings are but the sign of the poor fit that first became unmistakable when the first WXS drafts were released, and I'll be amazed if there's any magic nostrum to be brewed for this by Microsoft or anyone else. > - Could something like JSON become Yet Another Infoset Serialization > Format You Have To Deal With if binary XML gets momentum and opens up > the possibility of alternative serializations for different > environments?

It's a threat to XML for data exchange within Javascript (and rightly so).

I'm so glad that mad era does seem to be ending. If I were really feeling cheeky I'd propose XSLT2+XPath2 as counter-evidence, but I know better. XSLT2 does actually keep its place quite well. It's parts of XPath2 (and XQuery) that have gone off the rails, and neither is XML syntax. > - What happened to the "XML is text, dammit" advocates who used to > rant about how all this is misguided nonsense?

For my part I wish I had time to wind up for an "I told you so". I'm too busy in the sewers trying to clean up the damned pooling mess. It's no comfort that I believe I've foreseen the mess. If I were being inexcusably flip, I could say "I guess I know what a politically progressive soldier in Iraq feels like". In many ways I think a vicious backlash from programming languages against XML is just what XML needs right now. -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://fourthought.com http://copia.ogbuji.net http://4Suite.org Use CSS to display XML, part 2 - http://www-128.ibm.com/developerworks/edu/x-dw-x-xmlcss2-i.html XML Output with 4Suite & Amara - http://www.xml.com/pub/a/2005/04/20/py-xml.html Use XSLT to prepare XML for import into OpenOffice Calc - http://www.ibm.com/developerworks/xml/library/x-oocalc/ Schema standardization for top-down semantic transparency - http://www-128.ibm.com/developerworks/xml/library/x-think31.html
