Summary

So as you can see, by utilizing the JAXP API, code is written to interact directly with the abstraction layer. This guarantees vendor independence and the ability to swap out the backend implementation quickly and easily. In parsing an XML document, the Java developer has two options depending on their specific needs. SAX is an event-based parsing model that utilizes callback procedures, while DOM is a tree-walking model that parses the XML data into a tree before manipulating it. All in all, what we have in JAXP is a powerful, flexible, and easy to use set of tools that will meet the XML processing needs of most Java developers.
