What does SAX parser do?
SAX (Simple API for XML) is an event-based parser for XML documents. Unlike a DOM parser, a SAX parser creates no parse tree. Reads an XML document from top to bottom, recognizing the tokens that make up a well-formed XML document. Tokens are processed in the same order that they appear in the document.
How does SAX parser work example?
SAXParser provides method to parse XML document using event handlers. This class implements XMLReader interface and provides overloaded versions of parse() methods to read XML document from File, InputStream, SAX InputSource and String URI. The actual parsing is done by the Handler class.
In which cases we should use SAX parser?
When Should I Use SAX?
- When your documents are large.
- When you need to abort parsing.
- When you want to retrieve small amounts of information.
- When you want to create a new document structure.
- When you cannot afford the DOM overhead.
Which of the following method is used to get an instance of SAX parser from its factory?

Can we create an XML document using SAX parser?

What is difference between DOM and SAX parser in XML?
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.
What is difference between SAX and DOM parser?
Key Difference of DOM and SAX 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.
Which XML parser is more memory efficient?
SAX
SAX is more memory-efficient than DOM. DOM has its benefits, too. For example, DOM supports XPath. It makes it also easy to operate on the whole document tree at once since the document is loaded into memory.
What is SAXParseException in Java?

What is 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JAXP (Java API for XML Processing) is a rather outdated umbrella term covering the various low-level XML APIs in JavaSE, such as DOM, SAX and StAX.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.
