Question

Which XML parser performs event-oriented parsing?

• A. DOM parser
• B. SAX parser
• C. AJAX parser
• D. JSP parser

Hint:

DOM = Tree-based Parser SAX = Event-based Parser

Answer 1

The Correct Option is B

Concept: XML parsers are software tools that read XML documents and provide access to their contents. Two common XML parsers are:
• DOM Parser
• SAX Parser

Step 1: Understand SAX Parser.
SAX stands for: \[ \text{Simple API for XML} \] It processes XML sequentially and generates events whenever elements are encountered.

Step 2: Why Event-Oriented?
Events generated include:
• Start of document
• Start tag
• End tag
• End of document Applications respond to these events while parsing.

Step 3: Compare with DOM.
DOM loads the entire XML document into memory as a tree structure. SAX works through events and consumes less memory.

Step 4: Select the answer.
\[ \boxed{\text{SAX Parser}} \]
