XML Parser APIs: Tree-Based and Event-Based

• DOM (Document Object Model).

  • W3C recommended. Widely implemented, Tree-Based. Hierarchy of nodes. Loads entire document into memory (MSXML).

• DOM Level 2.

  • Candidate recommendation. Adds namespace support, traversal, stylesheets, events, triggers.

• SAX (Simple API for XML).

  • Open-source, XML-DEV, not W3C. Event-based, fires events as it reads document, need not load entire document into memory. Good for single-pass processing. Xerces, XML4C, Sun Project X (Crimson).
