How to remove element namespaces in XML file using DOM or SAX?

Question

Hi Guys,
I developed a JAVA mapping in XI to add name spaces for XML file, after mapping,name spaces xmlns="http://www.mro.com/mx/integration" and xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" were added correctly, but for some nodes, such as <Header> and <Content>, a name space xmlns="" was added automatically.Please check below files to compare.
It looks like be added automatically by XI. I didn't process anything for these nodes in JAVA program.
Now the issue is, how can I remove these redundant namespaces? Such as xmlns="".
Can I remove them using DOM or SAX in JAVA Mapping?
Thanks in advance.
====>Original XML file
<?xml version="1.0" encoding="UTF-8"?>
<LLYLPPInterface language="EN">
   <Header>

Hi Milan,
Thanks for your replay.
Actually when I used module XMLAnonymizerBean to convert namespaces, the header of XML, such as <?xml version="1.0" encoding="UTF-8"?> was converted to format <?xml version='1.0' encoding='UTF-8'?>, quote was converted to single quote. Although I set parameter anonymizer.quote = ", it still didn't work, single quote appeared instead of quote.
I'm not sure why this happened. Can anyone help to clarify this?
Thanks
