[jdom-interest] Small but irritating problem

[Jan-Olof Hendig]

Hello folks,

Just to get it over with, I'm an XML newbie so keep the flame throwers away for a while please.

Today I upgraded from JDOM beta 9 to the current release. As they say, better late than never :) My code needed very few changes in order to compile, the constructor for XMLOutputter had changed but that was easy to fix. However when running the code, see below, a small incompatibility surfaced. 

with beta 9 the code below produced the following

<?xml version="1.0" encoding="UTF-8"?>
<message>
   <request>
      <onlyreturnoutdata>0</onlyreturnoutdata>
   </request>
</message>

however with the current release I got

<?xml version="1.0" encoding="UTF-8"?>
<message xmlns:="">
   <request>
      <onlyreturnoutdata>0</onlyreturnoutdata>
   </request>
</message>

as you can see the line containing the <message> tag suddenly includes the attribute 'xmlns:=""'

My question is this, how do I get rid of this xmlns attribute so that the message looks exactly like it did in beta 9?

Regards

    transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "3");
   }
   else
       transformer.setOutputProperty(OutputKeys.INDENT, "no");
   transformer.transform(domSource, result);          
  } 
  catch (Exception e) {
   System.out.println(e);  
  }
  return stringWriter.toString();
 }
}
