Unlike DOM, SAX is event-based, so it does not build in-memory tree representations of input documents.SAX processes the input document element by element and can report events and significant data to callback methods in the application.Different parsers and tools support different schema languages such as DTDs, the W3C XML Schema Language, RELAX NG, and Schematron.

His Cafe au Lait Web site has become one of the most popular independent Java sites on the Internet, and his spin-off site, Cafe con Leche, has become one of the most popular XML sites. He's currently working on the XOM API for processing XML, the Jaxen XPath engine, and the Jester test coverage tool.

Configure Java APIs (SAX, DOM, dom4j, XOM) using JAXP 1.3 to validate XML Documents with DTD and Schema(s).

This relieves problems of memory inefficiency, limited scalability, and lack of control over the DOM configuration.

For the scalable DOM, the configuration and creation are mainly supported using the interfaces.

JAXP provides support for XML schema and an XSLT compiler.

You can access the JAXP specification, which is produced by Sun Microsystems, at the following URL: DOM Stream access to XML nodes is done by PL/SQL and Java APIs.You can use parsing in validating or nonvalidating mode.This chapter assumes that you are familiar with the following technologies: JAXP version 1.2 includes an XSLT framework plus some updates to the parsing API to support DOM Level 2 and SAX version 2.0 and an improved scheme to locate pluggable implementations.DOM provides classes and methods to navigate and process the tree.In general, the DOM API provides the following advantages: Release 1 (11.1), XDK provides scalable, pluggable support for DOM.
