Difference between SAX parser and DOM parser ?

SAX Parser :

• Sax is read only parser.
• Sax follows event driven model.
• Using Sax you can read the data sequentially.
• Sax occupies very less memory because only one element information will be stored in the memory at a time.

DOM Parser :

• Dom is read write parser.
• Dom follows tree model.
• Using Dom you can read the data randomly.
• Dom occupies more memory because entire object graph and memory will be loaded in main memory at a time.
