Answer / harish
DOM Parser is nothing but, Document Object Model Parser, It
loads the entire XML file into the primary memory and
represents in a Tree structured manner. It traverses from
Root Node to Child Node.
SAX Parser is nothing but, Simple API for XML. It is event
driven based parser. It traverse node by node in a
sequential order. It won?t load the entire xml file into
the memory. If it is small xml file, better go for DOM
Parser. If it huge xml file, better go for SAX Parser.

Answer / sangeri
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

SAX is top to bottom traversal as it parse node by node
DOM traverse in any direction because the whole XML while
gets loaded into the memory.

DOM is top to bottom traversal as it parse node by node
SAX traverse in any direction because the whole XML while
gets loaded into the memory.
And thats why SAX is faster than DOM.
