SAX (Simple API for XML) is an event-driven online algorithm for lexing and parsing XML documents, with an API developed by the XML-DEV mailing list. [1] SAX provides a mechanism for reading data from an XML document that is an alternative to that provided by the Document Object Model (DOM).
Unlike the DOM parser, the SAX parser does not create an in-memory representation of the XML document and so runs faster and uses less memory. Instead, the SAX parser informs clients of the XML document structure by invoking callbacks, that is, by invoking methods on an DefaultHandler instance provided to the parser.
Catalog resolvers are available for various programming languages. The following example shows how, in Java, a SAX parser may be created to parse some input source in which the org.apache.xml.resolver.tools.CatalogResolver is used to resolve external entities to locally cached instances
Projects incorporating the Expat library often build SAX and possibly DOM parsers on top of Expat. While Expat is mainly a stream-based (push) parser, it supports stopping and restarting parsing at arbitrary times, thus making the implementation of a pull parser relatively easy as well.

In computing, Xerces is Apache's collection of software libraries for parsing, validating, serializing and manipulating XML. The library implements a number of standard APIs for XML parsing, including DOM, SAX and SAX2. The implementation is available in the Java, C++ and Perl programming languages.
A pull parser creates an iterator that sequentially visits the various elements, attributes, and data in an XML document. Code that uses this iterator can test the current item (to tell, for example, whether it is a start-tag or end-tag, or text), and inspect its attributes (local name, namespace , values of XML attributes, value of text, etc ...
JDOM integrates with Document Object Model (DOM) and Simple API for XML (SAX), supports XPath and XSLT. [2] It uses external parsers to build documents. JDOM was developed by Jason Hunter and Brett McLaughlin starting in March 2000. [3] It has been part of the Java Community Process as JSR 102, though that effort has since been abandoned. [4]
