SAX stands for Simple API for XML, and is a different method to parse the XML. The parser goes through the XML file and triggers event for everything it encounters. For example when it finds an opening tag, it triggers an event, when it finds an attribute, it triggers another one, when it reaches a text node then another, when it reaches the end of the tag then another. So it sequentially parses the XML file triggering event for everything it encounters within the XML during parsing. It is really fast, but it is sequential, so you cannot go back and forward withing the XML with it. If you want to do another run in the XML, you have to parse the whole XML another time, or you build a DOM like document during the SAX parsing. -- Poetro -- To view archived discussions from the original JSMentors Mailman list: http://www.mail-archive.com/jsmentors@jsmentors.com/ To search via a non-Google archive, visit here: http://www.mail-archive.com/jsmentors@googlegroups.com/ To unsubscribe from this group, send email to jsmentors+unsubscr...@googlegroups.com
