Support for XML was primarily through third-party libraries (such as Apache Xerces or JDOM).Fortunately, that has changed, and now you can get the Java XML Pack, a toolset for dealing with everything XML in Java. These reader and writer classes are used to read and write XMl documents. In this article, we are going to concentrate on reader and write class. Then, you will see how to read and write XML documents. It also contains properties to get a parent or child, name, last child, node type and more. XPath Namespce contains XPath related classes to use XPath specifications. This class is an abstract base class for many useful classes for inserting, removing, and replacing nodes, navigating through the document. The Xml Write class contains functionality to write data to XML documents.
The SAX parser is based on a push model, wherein the parser pushes events to content handlers.The XML Pack brings together several of the key industry standards for XML, such as SAX, DOM, XSLT, SOAP, Universal Description, Discovery & Integration (UDDI), Electronic Business using Extensible Markup Language (eb XML), and Web Services Description Language (WSDL).The two common programmatic XML APIs (SAX and DOM) are now built into the core Java API (as of J2SE 1.4.0).The DOM parser parses the XML into an in-memory tree data structure (also known as a DOM tree).The Document Object Model is an API for valid HTML and well-formed XML documents.
