Reducing code redundancy while creating XML with XOM

I am using XOM as my XML parsing library. And i am using this for creating XML also. Below is the scenario described with example.

Scenario:

Code:

Element root =  new Element("atom:entry", "http://www.w3c.org/Atom");
Element city = new Element("info:city", "http://www.myinfo.com/Info");
city.appendChild("My City");
root.appendChild(city);     
Document d = new Document(root);
System.out.println(d.toXML());

Generated XML:

<?xml version="1.0"?>
<atom:entry xmlns:atom="http://www.w3c.org/Atom">
   <info:city xmlns:info="http://www.myinfo.com/Info">
       My City
   </info:city>
</atom:entry>

Notice in the XML that here info namespace is added with the node itself. But I need this to be added in root element. like below

<?xml version="1.0"?>
<atom:entry xmlns:atom="http://www.w3c.org/Atom" xmlns:info="http://www.myinfo.com/Info">
   <info:city>
       My City
   </info:city>
</atom:entry>

And to do that, i just need following piece of code

Element root =  new Element("atom:entry", "http://www.w3c.org/Atom");
=> root.addNamespaceDeclaration("info", "http://www.myinfo.com/Info");
Element city = new Element("info:city", "http://www.myinfo.com/Info");
... ... ...

Problem is here i had to add http://www.myinfo.com/Info twice. And in my case there are hundreds of namespaces. So there will so too much redendancy. Is there any way to get rid of this redundancy?

No, there is no way to get rid of this redundancy and that's a deliberate decision. In XOM the namespace is a fundamental part of the element itself, not a function of its position in the document.

Of course you could always declare a named constant for the namespace URI.
