How to create new DOM tree with fully qualified element names |
|
|
In the same way as for loading namespaces may be used while constructing new
DOM-documents. The only difference is that you have to manage namespaces manually.
Besides not of all DOM-serializer implementations support automatic namespace-prefix
generation. Thus it is good idea to declare your namespace as default one on you
root element. This is shown in the following sample:
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
/**
* This sample program using fully qualified names while
* creating the contents of DOM-document.
*/
public class Test {
public static void main(String[] args) {
try {
// load the document from a file:
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
DocumentBuilder loader = factory.newDocumentBuilder();
Document document = loader.newDocument();
// here is our vendor URL used in namepace-related functions:
String docNS = "http://www.my-company.com";
// create document element:
Element order = document.createElementNS(docNS,
"purchase-order");
document.appendChild(order);
// set default namespace:
order.setAttribute("xmlns", docNS);
// .. create some other contents ...
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
