how to use namespace?

[GoogleCodeExporter]

As it is said in API References that "Namespace nodes are not supported"
then how are they implemented in pugixml?

I am trying to convert MSXML into pugixml? Function i am trying to convert is 
as under

CDS_RETVAL CXmlDocument::CreateElement(const std::wstring& name, const 
std::wstring& prefix, const std::wstring& nameSpace, CXmlNode& element)
{
   CDS_RETVAL retVal;
   CComBSTR name_space;
   CComBSTR node_name;
   CComVariant type;
   std::wstring prefix_name;
   CComBSTR bstr_prefix_name;
   HRESULT hr;

   retVal = OK;
   type.vt = VT_I4;

   //Create node name with prefix
   prefix_name = prefix + std::wstring(TEXT(":")) + name;

   if (NULL != element.m_XmlNode)
   {
#ifdef DEBUG
      assert(0);
#else
      m_log.AddLog(cModuleUtility, cLevelError, "MEMORY LEAK in CXmlDocument::CreateElement");
#endif
   }

   //Create the element
   type = NODE_ELEMENT;
   name_space = nameSpace.c_str();
   node_name = name.c_str();
   bstr_prefix_name = prefix_name.c_str();
   hr = m_XmlDocument->createNode(type, bstr_prefix_name, name_space, &(element.m_XmlNode));
   if (FAILED(hr))
   { 
      retVal = CDS_ERROR_UNKNOWN; goto CleanUp;
   }

CleanUp:

   return retVal;
}

You can use namespaces in pugixml just fine - it's similar to what you're doing 
in your code, i.e. just create a child with name that contains a semicolon 
(and, if necessary, add an xmlns attribute).

I.e.:
pugi::xml_node child = node.append_child("test:nodename");
child.append_attribute("xmlns") = "http://test.org";

The documentation is referring to namespace nodes in XPath - this is a special 
concept that is only important for a small fraction of XPath documents, see 
http://www.w3.org/TR/xpath/#namespace-nodes
