The XML DOM (Document Object Model ) is used for accessing and manipulating XML documents. In it XML elements can be created and added as node objects to the XML tree structure.

There are two basic type of XMl parser:

  • Tree-based parser

    The tree based parser is used to load the entire XML document into memory and provides access to the tree element. e.g, Document object model (DOM).
     
  • Event based parser

    Event based parser is used when a specific event occurs, it call a function to handle it.
