DOM parser
1.In DOM parser the representation is in the memory as it
is used for the internal representation of an
XML document.
2.It reads the whole document and returns a DOM tree
representation of the
XML document.
3.So for smaller xml we can use DOM as memory is the
constraint.
SAX parser
1.It is event driven
2.It works incrementally and generates events that are
passed to the application.
3.For huge
XML we can go for SAX rather than DOM
4.It does not give any structural representation for the
XML document.
So depending on the application you develop you can choose
any of the parser
