SAX (Simple API for XML):

☛ Parses node by node

☛ Doesn't store the XML in memory

☛ We can not insert or delete a node

☛ Top to bottom traversing

DOM (Document Object Model):

☛ Stores the entire XML document into memory before processing

☛ Occupies more memory

☛ We can insert or delete nodes

☛ Traverse in any direction
