Hi BR,
I think what you are looking for is the JAXB binder method, that can
map a JAXB element to a document, then you can use XPath on the doc,
then the binder will sync the changes:
try {
JAXBContext jaxbContext = JAXBContext.newInstance( com.blah.blah.MyType.class );
QName qname = new QName("
http://www.example.com/schema", "myObject");
Binder<Node> binder = jaxbContext.createBinder();
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
//dbf.setNamespaceAware(false); // This was tested and does not work,
needs a namespace context
dbf.setValidating(false);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.newDocument();
//Binder will maintains association between two views.
binder.marshal( new JAXBElement<MyType>(qname,
com.blah.blah.MyType.class, MyType), doc );
XPath xpath = XPathFactory.newInstance().newXPath();
xpath.setNamespaceContext( new MyNamespaceContext() );
// Example xpath
//Node node = (Node) xpath.evaluate("/ns:thing", doc,
XPathConstants.NODE );
Node n = (Node) xpath.evaluate( path, doc, XPathConstants.NODE );
if (n != null) {
n.setTextContent( text );
}
// And here is where you sync things up
binder.updateJAXB( doc );
} catch( Exception e ) {
//e.printStackTrace();
log.error( e.getClass() + ": " + e.getMessage() );
return null;
}
// These are the specific exceptions:
//catch (JAXBException e) {
// e.printStackTrace();
//} catch (XPathExpressionException e) {
// e.printStackTrace();
//} catch (ParserConfigurationException e) {
// e.printStackTrace();
//} catch (TransformerException e) {
// e.printStackTrace();
//}
//
Regards,
Hank
