SAX Parser

A SAX (Simple API for XML) parser is a tool used to read and process XML files efficiently. It works by scanning through the XML document sequentially, detecting elements, tags, and data as it goes. Unlike some other methods, SAX doesn’t load the entire file into memory but processes it in small parts, making it suitable for large files or streaming data. It triggers specific events when it encounters different components, allowing programs to respond dynamically. This approach is fast and memory-efficient, making it ideal for applications that need quick, lightweight XML processing.
