When you write a SAX application, you need to keep crossbreed of your programs position in the document roughlywhere in your accord code. SAX does not do it for you. Also, if you need to look forrard in the XML document, you are just out of luck. Some applications are scarcely impossible in an event driven feign with no access to a tree. Of course you could build some bod of tree yourself in SAX events, but the DOM allows you to stave off musical composition that code. The DOM is a standard tree delegation for XML data. The Document Object Model Levels 0 & 1 are soon unspoilt W3C recommendations. The Document Object Model Level 2 is currently a Working Draft, and is rout to change.
