XOM API for Processing XML with Java

["Kevin S. Clarke" <ksclarke AT stanford.edu>]

Hi,

I am getting a blank namespace when I serialize a document. I want a
default namespace that is not repeated on each element so I set it on
root.  I also add another namespace declaration with prefix that I can
use on deep children (with the URI also declared on the root element).

// Currently, Serializer.java says:

String uri = element.getNamespaceURI(additionalPrefix);
if (parentNode instanceof Element) {
  Element parentElement = (Element) parentNode;
  if (uri.equals(parentElement.getNamespaceURI(additionalPrefix))) {
    // I added brackets b/c this wrapped in my email client
    continue;
  }
}
else if (uri.equals("")) {
  continue; // no need to say xmlns=""
}

// If it said instead:

String uri = element.getNamespaceURI(additionalPrefix);
if (uri.equals("")) {
  continue; // no need to say xmlns=""
}
else if (parentNode instanceof Element) {
  Element parentElement = (Element) parentNode;
  if (uri.equals(parentElement.getNamespaceURI(additionalPrefix))) {
    // I added brackets b/c this wrapped in my email client
    continue;
  }
}

// end

there would be no problem (but I haven't thought this through so it may
introduce other problems farther down)... If I'm missing something big
just let me know...

Thanks,
Kevin


--sample code--
import nu.xom.Serializer;
import nu.xom.Document;
import nu.xom.Element;

import java.io.IOException;

public class Test {
    public static void main(String[] args) throws IOException {
        Serializer writer = new Serializer(System.out);
        Element root = new Element("root");
        Document document = new Document(root);
        String fakeNS = "http://fake.com/namespace";;
        
        root.addNamespaceDeclaration("fake", fakeNS);
        root.setNamespaceURI("http://default.com/namespace/";);
        
        Element e1 = new Element("e1");
        Element e2 = new Element("e2");
        Element e3 = new Element("e3");
        Element e4 = new Element("fake:e4", fakeNS);
        
        e2.appendChild(e3);
        e2.appendChild(e4);
        e1.appendChild(e2);
        root.appendChild(e1);
        
        writer.setIndent(4);
        writer.write(document);
    }
}

--sample result--
<?xml version="1.0" encoding="UTF-8"?>
<root xmlns="http://www.loc.gov/mods/";
xmlns:fake="http://fake.com/namespace";>
    <e1 xmlns="">
        <e2>
            <e3/>
            <fake:e4/>
        </e2>
    </e1>
</root>
