This hierarchical tree structure is called a Document Object Model (DOM) tree, and an XML parser that creates such a tree is known as a DOM parser. DOM gets its name from the conversion of an XML document’s tree structure into a tree of objects that are then manipulated using an object-oriented programming ...
