             Summary: Generate DOM Element with empty namespace using Apache 
xerces 
                 Key: XERCESJ-1720
                 URL: https://issues.apache.org/jira/browse/XERCESJ-1720
             Project: Xerces2-J
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 2.8.1
            Reporter: Vithursa


I have a requirement to generate an XML which should have empty namespace. An 
example XML should looks like:
{code:xml}
<name  xmlns:cap="http://sap.com/xi/BASIS";>      
   <cap:attributeID>            
      <attribute1 xmlns="" >xxxx</attribute1>            
      <attribute2 xmlns="" >xxxx</attribute2>      
   </cap:attributeID> 
</name>
{code}
 
 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:
{code:java}
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>.
{code}
{code:java}
element = doc.createElementNS("", "name"); // Output : 
<attribute1>xxxx</attribute1>
{code}
{code:java}
element = doc.createElement("name");
element.setAttribute("xmlns", "");  // Output : <attribute1>xxxx</attribute1>
{code}
{code:java}
element = doc.createElement("name");
element.setAttributeNS("http://www.w3.org/2000/xmlns/";, "xmlns", "");
// Output : <attribute1>xxxx</attribute1>
{code}
What is the correct way of adding an empty string as namespace to cater my 
requirement? Can someone provide guidance on this?

Thanks,
 Vithursa
