XML Processing
XML APIs have always been available to the Java developer, usually supplied as third-
party libraries that could be added to the runtime class path. Beginning in Java 7, the
Java API for XML Processing (JAXP), Java API for XML Binding (JAXB), and the
Java API for XML Web Services (JAX-WS) were included in the core runtime libraries.
The most fundamental XML processing tasks that you will encounter involve only a few
use cases: writing and reading XML documents, validating those documents, and using
JAXB to assist in marshalling/unmarshalling Java objects. This chapter provides recipes
for these common tasks.
