  Simple API for XML - Wikipedia, the free encyclopedia
This is attributed to the fact that a SAX stream has a minuscule memory footprint compared to that of a fully constructed DOM tree.
The SAX parser is implemented as an event-driven model in which the programmer provides callback methods which are invoked by the parser as part of its traversal of the XML document.
SAX was developed collaboratively on the xml-dev mailing list, with no formal committee structure, but was quickly implemented by major companies working with XML.

 5 SAX: The Simple API for XML
SAX is most suitable for purposes where you want to read through an entire XML document from beginning to end, and perform some computation such as building a data structure or summarizing the contained information (computing an average value of a certain element, for example).
SAX is not very convenient if you want to modify the document structure by changing how elements are nested, though it would be straightforward to write a SAX program that simply changed element contents or attributes.
Another advantage of SAX is that you don't have the whole document resident in memory at any one time, which matters if you are processing really huge documents.

 3 SAX: The Simple API for XML
The Simple API for XML isn't a standard in the formal sense, but an informal specification designed by David Megginson, with input from many people on the xml-dev mailing list.
SAX is most suitable for purposes where you want to read through an entire XML document from beginning to end, and perform some computation, such as building a data structure representating a document, or summarizing information in a document (computing an average value of a certain element, for example).
SAX defines 4 basic interfaces; an SAX-compliant XML parser can be passed any objects that support these interfaces, and will call various methods as data is processed.

 The XML Files: SAX, the Simple API for XML -- MSDN Magazine, November 2000
SAX is similar to firehose-mode cursors (read-only and forward-only) while DOM is closer to a static cursor that allows full traversal and updates.
SAX processors are required to report namespace names (namespace URI plus local name) if the namespace and namespace-prefixes properties are set properly, but they are not required to report QNames by default.
SAX defines several well-known features and properties that SAX processors are encouraged to recognize, although not all of the standard features or properties make sense for all implementations.

SAX (Simple API for XML) like DOM (Document Object Model) gives access to the information stored in XML documents using any programming language (and a parser for that language).
SAX 1.0 (the Simple API for XML) was released on May 11, 1998.
SAX is a common, event-based API for parsing XML documents, developed as a collaborative project of the members of the XML-DEV discussion under the leadership of David Megginson.

 The skew.org XML Tutorial
XML documents, in order to be stored or transmitted, must manifest in an encoded form as bits and bytes, using a consistent character encoding mechanism such as UTF-16 or UTF-8.
SAX (Simple API for XML) is a de facto standard that defines a convention for parsers to report the logical contents to an application.
An XML parser that is not validating an XML document is not required to read any external entities, so in some situations it is not an error for a document to refer to an entity that is declared in one of those entities.

 XML.com: High-Performance XML Parsing With SAX
SAX (Simple API for XML) is an event-driven model for processing XML.
The behavior of character events often misleads newcomers to SAX who usually expect the entire contents of an element to be delivered in one lump to the handler.
SAX handlers can be, and often are, far more complex than the one here, but this example illustrates the fundamentals of SAX processing.

 The Simple API for XML   (Site not responding. Last check: 2007-10-29)
SAX a is a sequential, event driven, stateless (and therefore read-only) parsing strategy.
The client application registers its interest in selected XML element and defines the respective call-back methods.
When parsing occurs, the document is processed sequentially and the relevant call-back method is invoked whenever the corresponding XML element is encountered.

XML 1.0 is defined by the XML 1.0 Recommendation from the World Wide Web Consortium (W3C), and is used as the basis for a number of related specifications and recommendations.
Working programmatically with XML data requires the use of a parser—an application that reads the document and breaks it into its component parts for interpretation according to a particular model.

 WDVL: XML and Java: SAX: Simple API for XML (Parsers)
SAX stands for "Simple API for XML"; it is an extremely popular (almost ubiquitous) event-based interface for any XML parser.
SAX is somewhat of a grass-roots effort, spearheaded by David Megginson, of the xml-dev mailing list.
SAX uses an event-driven model: the parser identifies an element, resulting in that element's event handler being invoked.

 Working with XML: The Java/XML Tutorial
Serial Access with the Simple API for XML (SAX) walks you through the process of creating an XML file and tells you how to read it sequentially, walking you through the callbacks the parser makes to event-handling methods you supply.
XML and the Document Object Model (DOM) explains how to create and manipulate a hierarchy of data objects so you can randomly access it and modify its contents.
This is also the API you use to write an XML file from a tree of objects in memory, and to create XML from an arbitrary document structure.

 Simple API for XML
Note: In a nutshell, SAX is oriented towards state independent processing, where the handling of an element does not depend on the elements that came before.
SAX is an event-driven model (you provide the callback methods, and the parser invokes them as it reads the XML data), and that makes it harder to visualize.
For those reasons, developers who are writing a user-oriented application that displays an XML document and possibly modifies it will want to use the DOM mechanism described in Chapter 6.

The XML standard is very clear on the issue of non-compliant documents.
It does support converting XML into a Perl tree structure (with full support for mixed content) but for arbritrarily large documents you're probably better off defining handler routines for XML::Parser to call as each element is parsed.

 Simple API for XML
This is the protocol that most servlets and network-oriented programs will want to use to transmit and receive XML documents, because it's the fastest and least memory-intensive mechanism that is currently available for dealing with XML documents.
For those reasons, developers who are writing a user-oriented application that displays an XML document and possibly modifies it will want to use the DOM mechanism described in the next part of the tutorial, Document Object Model.
When parsing a document for a DOM, the same kinds of exceptions are generated, so the error handling for JAXP SAX and DOM applications are identical.

 SAX - The Simple API for XML
The Simple API for XML (SAX is a low-level, event-driven or event-based system which operates in a fashion similar to a Graphical User Interface (GUI).

Many parsers support SAX, so if you prefer event-driven systems, this may be a reasonable choice for you.
