Difference among XML SAX parser, Pull parser & DOM parser

Sax Parser : Simple API of XML Parse node to node, using top-down traversing, parse without storing xml, Faster compared to Dom Manipulating of node like insertion or deletion is allowed. Needs SAXParserFactory

Dom Parser : Document Object Model Stores entire xml in memory before processing, traverse in any direction, Manipulating of node like insertion or deletion is NOT allowed. Needs DocumentBuilderFactory

Pull Parser: It provides more control and speed from the above two.
