JAXB: Deserializing an xml string for unit tests

Sometimes it is useful to take a copy of an xml to help setup data for unit tests. The following is a snippet you could use

String rsXml = "    <SampleResponse xmlns=\"http://example.com/sample/\">\n" +
        "      <header>\n" +
        "        <version>2.3</version>\n" +
        "      </header>\n" +
        "      <body>\n" +
        "        <transactionStatus code=\"08\">\n" +
        "        </transactionStatus>\n" +
        "      </body>\n" +
        "    </SampleResponse>";
JAXBContext jaxbContext = JAXBContext.newInstance(SampleResponse.class);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
SampleResponse response = (SampleResponse) unmarshaller.unmarshal(new ByteArrayInputStream(rsXml.getBytes()));

It is assumed you have already generated jaxb Java classes from the xsd.
