Well, that's good news for you at least :-) but note that xqilla is not optimized unless you use it with dbxml. Otherwise, it's one of the slower XQuery implementations I've tried (and I've tried quite a few). Sometimes one program is faster and sometimes another. Overall, libxml + xsltproc is pretty fast for what it does, although I've measured a 100 times speedup moving to Saxon (XSLT 2 in Java) in some cases. XQilla + dbxml gets its win because it only parses the XML once, and then stores it in a database with an index (but you have to enable the index or it won't be much faster). This is only a win if you process the same XML document multiple times of course. So you always have to look at the bigger picture Liam -- Liam Quin - XML Activity Lead, W3C, http://www.w3.org/People/Quin/ Pictures from old books: http://fromoldbooks.org/ Ankh: irc.sorcery.net irc.gnome.org freenode/#xml _______________________________________________ xml mailing list, project page http://xmlsoft.org/ [email protected] https://mail.gnome.org/mailman/listinfo/xml
