As defined by JSR-05, JAXP defines a standard way to manipulate XML documents. JAXP supports event based parsing (SAX style) as well as in-memory trees (DOM style). It also includes ability to print an XML document as well as to support XML Namespaces it required. With JAXP, application developers have the flexibility to swap between XML processors (such as high performance vs. memory conservative parsers) without making application code changes.

JAXP is one of the API’s in the Java Web Serviced Developer Pack.
