Querying Objects by XPath

With EclipseLink MOXy, you do not have to use normal Javabean access methods to get and set values. Instead, you can use the APIs on the JAXBContext itself, at runtime.

For example, instead of:

    Customer customer = (Customer) jaxbContext.createUnmarshaller().unmarshal(instanceDoc);
    int customerId = customer.getId();
    customer.setFirstName("Bob");
    customer.getPhoneNumber().setAreaCode("555");
    jaxbContext.createMarshaller().marshal(customer, System.out);

You could use XPath to access these values:

    Customer customer = (Customer) jaxbContext.createUnmarshaller().unmarshal(instanceDoc);
    int customerId = jaxbContext.getValueByXPath(customer, "@id", null, Integer.class);
    jaxbContext.setValueByXPath(customer, "first-name/text()", null, "Bob");
    jaxbContext.setValueByXPath(customer, "phone-number/area-code/text()", null, "555");
    jaxbContext.createMarshaller().marshal(customer, System.out);
