Overview
The StAX (Streaming) API provide streaming, event-driven, pull parsing for reading and writing XML documents, as an alternative to SAX push parsing and JAXP DOM full in-memory tree structure representation. StAX has an iterator-based API, where the programmer asks for the next element (pulls the event), and also a cursor-based API.
StAX parsers can be used for state-dependent processing, unlike SAX parses, which can only be used for state-independent processing.
StAX is a read/write API, XML documents can be read and written with StAX.
StAX offers a simpler programming model than SAX and more efficient memory management than JAXP DOM.
Difference between Pull Parsing and Push Parsing

Iterator-Based API
StAX Example
Component Packages
- javax.xml.stream defines the XMLStreamReader and XMLStreamWriter interfaces.
- javax.xml.transform.stax provide StAX specific transformation APIs.
