Jackson is "the Java JSON library" or "the best JSON parser for Java". Or simply as "JSON for Java".

Jackson also allows you to parse or generate XML messages with the Jackson Dataformat XML Extension.

Jackson Dataformat XML Source Code files are provided in the source packge (jackson-dataformat-xml-2.12.4-sources.jar). You can download it at Jackson Maven Website.

You can also browse Jackson Dataformat XML Source Code below:

/**
 * Annotation that can be used to provide XML-specific configuration
 * for properties, above and beyond what
 * {@link com.fasterxml.jackson.annotation.JsonProperty} contains.
 * It is mainly an alternative to using JAXB annotations.
 *<p>
 * Note that annotation may be used on
 *<ul>
 * <li>Fields
 *  </li>
 * <li>Setter and getter methods
 *  </li>
 * <li>Arguments (parameters) of "Creators" -- annotated constructors and/or
 *    static factory methods
 *  </li>
 * </ul>
 * but it can NOT be used on argument/parameter of setter methods (or rather
 * while compiler allows that, will have no effect) -- setter method itself
 * needs to be annotated.
 *<p>
 * Note that since 2.12 there is no need to use this property over
 * {@link com.fasterxml.jackson.annotation.JsonProperty} just to define XML namespace,
 * as {@code @JsonProperty} has {@code namespace} property.
