Map to Element based on an Attribute Value with EclipseLink JAXB (MOXy)

This is the complete source code for the following blog post:

Summary

In EclipseLink 2.3 the @XmlPath annotation was enhanced to support predicates. This allows us to map the class below:

@XmlRootElement(name="node")
public class Customer {

    @XmlPath("node[@name='name']/text()")
    private String name;

    @XmlPath("node[@name='address']")
    private Address address;

    @XmlPath("node[@name='phone-number']")
    private List<PhoneNumber> phoneNumbers;

}

To the following XML:

<?xml version="1.0" encoding="UTF-8"?>
<node>
    <node name="name">Jane Doe</node>
    <node name="address">
        <node name="street">123 A Street</node>
    </node>
    <node name="phone-number" type="work">555-1111</node>
    <node name="phone-number" type="cell">555-2222</node>
</node>
