(Does Zope 2.3.2+ ship with a fast XML parser? If so, what's it called and where do I import it from?)
Just because you mentioned "fast": Am I doing any thing wrong, or is ParsedXML extremely slow? The tests I did were not really reliable, but even with a fast Pentium III machine (800 MHz, a lot of RAM), switching between the edit view and the DOM view can take a couple of seconds for me. And that's for really simple, ten-line test XML documents.
That's way slower than what I've seen. The edit or DOM tree view of a ten-line XML document should not be noticably slower than your average Zope management page on a fast machine. I test on a 666 Mhz box with lots of other stuff going on and don't see this. If you're looking at the *collapsed* DOM tree view, ParsedXML isn't doing much at all, just getting the document element node, so slowness that you see there probably isn't ParsedXML. Access these pages and some DTML documents or whatever *on the same server with the same load* with wget or ab, and time the results. What is the difference? That being said, printing the XML is slow, which is why the default view isn't the edit window. I recommend cacheing when you're using the XML from ParsedXML. And also, yes, ParsedXML proxies the DOM in an clunky way, which is why it is often a good idea to use the proxied DOM when speed is an issue. It's a compromise. ParsedXML's proxy layer has the features, the proxied DOM has the speed, but is nothing but DOM. -- Karl Anderson karl@digicool.com
