Patrizio -----Original Message----- From: Cezar Andrei [mailto:[EMAIL PROTECTED] Sent: martedì, 10. aprile 2007 23:49 To: [email protected] Subject: RE: XMLBeans and XmlCursor Hi Patrizio, Depending on how complex you xpath will be executed by an internal XMLBeans engine or Saxon engine. The XMLBeans xpath engine is usually much faster but supports a very limited subset of xpath. Saxon on the other hand is more complete but since it uses XMLBeans store as a DOM it usually is slower. But even for Saxon 3s for a 400k doc is kind of much on today's procs, but again how complex is the xpath?
