From a performance point of view, one can imagine a factory object that given xml queries, generates optimal code for executing them. That clearly could be a lot more efficient than DOM in many many cases. -----Original Message----- From: noah_mendelsohn@us.ibm.com [mailto:noah_mendelsohn@us.ibm.com] Sent: Wednesday, August 28, 2002 7:52 AM To: Kay, Michael Cc: eamon.otuathail@clipcode.com; www-ql@w3.org Subject: RE: Could XQuery replace the W3C DOM? DOM is already somewhat slow/heavyweight for certain purposes. While I'm sure a lot of good work will be done on query implementation and optimization, it's not immediately clear that a query-based implementation would in practice be more rather than less efficient compared to DOM. Not that it's a bad idea in principle, but performance is a significant barrier to adoption of XML for purposes such as SOAP, and we do need to pay more attention to performance as APIs evolve, IMO.
