Document Object Model Document Object Model (DOM): Defines programming interfaces for accessing and changing an XML document as a tree structure Is defined by a W3C recommendation DOM API: Is platform- and language-independent Stores an entire XML document tree in memory Can dynamically access and update the content, structure, and style of documents Level 2 provides specialized interfaces dedicated to XML

11. I-11 Copyright © 2004, Oracle. All rights reserved. Simple API for XML Simple API for XML (SAX): Is an event-based API for reading XML documents Reads a document as a serialized (ordered) event stream of data Uses events to notify programs when it detects document objects, such as start and end tags Does not store the document in memory and does not support random-access manipulation Is a good choice for processing very large documents Is developed independently of W3C
