What is the difference between JAXB and Jaxp?

JAXP (Java API for XML Processing) is a rather outdated umbrella term covering the various low-level XML APIs in JavaSE, such as DOM, SAX and StAX. JAXB (Java Architecture for XML Binding) is a specific API (the stuff under javax. xml. bind ) that uses annotations to bind XML documents to a java object model.

What is Xerces jar used for?

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.

Does Jaxb use DOM or SAX?

Implementations of JAXB will most likely use a DOM or SAX parser behind the scenes to do the actual parsing of the XML input data. Often you’ll want to convert the content of an XML document into objects in your Java program.

What is produced by a SAX parser?

This XML document, when passed through a SAX parser, will generate a sequence of events like the following: XML Element start, named DocumentElement, with an attribute param equal to “value” XML Element start, named FirstElement.

Why is JAXB used?

JAXB allows Java developers to access and process XML data without having to know XML or XML processing. For example, there’s no need to create or use a SAX parser or write callback methods.

What is DOM and SAX parser?

DOM stands for Document Object Model while SAX stands for Simple API for XML parsing. DOM parser load full XML file in-memory and creates a tree representation of XML document, while SAX is an event based XML parser and doesn’t load whole XML document into memory.

How does a SAX parser work?

A SAX parser never creates a tree structure for the document in memory. Because the application that calls SAX receives an event each time the parser encounters a significant XML symbol, the application can use this information to create a tree structure in memory.
