XML News from Thursday, April 15, 2004

The W3C DOM working group has released the final Document Object Model (DOM) Level 3 Core Specification and the Document Object Model (DOM) Level 3 Load and Save Specification. The load and save specification defines platform and language independent means to parse an XML document to create a DOM Document object, and to serialize DOM Document objects into a file or output stream, something that was previously implementation dependent and accomplished with APIs like JAXP. DOM Level 3 Core adds various new features and methods to the standard DOM classes including:

• Base URI support
• A standard bootstrapping procedure to load a DOMImplementation in Java by reading a DOMImplementationRegistry
• A DOMConfiguration interface that controls lots of little fiddly details like normalization
• The XML declaration information such as encoding is now available in the Document object
• User data attached to nodes
• You can get the whole text from a text node.
• DOMErrorHandler for reporting errors (like SAX2's ErrorHandler)
• DOMLocator interface for reporting document positions (like SAX2's Locator)
• A TypeInfo interface for DTDs and schemas
