Description

I have a requirement to generate an XML which should have empty namespace. An example XML should looks like:

<name  xmlns:cap="mynamespace">      
   <cap:attributeID>            
      <attribute1 xmlns="" >xxxx</attribute1>            
      <attribute2 xmlns="" >xxxx</attribute2>      
   </cap:attributeID> 
</name>

 
As mentioned above, I need to add xmlns attribute with empty string. I have tried following ways to achieve it but none of them worked:

DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder;
docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.newDocument(); 

element = doc.createElement("attribute1");  // It did not have any namespace. Output becomes as,  <attribute1>xxxx</attribute1>.

element = doc.createElementNS("", "name"); // Output : <attribute1>xxxx</attribute1>

element = doc.createElement("name");
element.setAttribute("xmlns", "");  // Output : <attribute1>xxxx</attribute1>

element = doc.createElement("name");
element.setAttributeNS("http://www.w3.org/2000/xmlns/", "xmlns", "");
// Output : <attribute1>xxxx</attribute1>

What is the correct way of adding an empty string as namespace to cater my requirement? Can someone provide guidance on this?

Thanks,
