Convert String to InputStream

InputStream is = null;
try {
is = new ByteArrayInputStream("yourTestXML".getBytes("UTF-8"));
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
這樣就可以用在jaxb來parse XML
JAXBContext context = JAXBContext.newInstance(DailyRes.class);
Unmarshaller u = context.createUnmarshaller();
Object result = u.unmarshal(is);
