Saving a IXMLDOMDocument without end tag

Using MSXML via C++, when I call IXMLDOMDocument::save, empty XML elements will get an end tag, like this:

<root>
    <child name="first">
    </child>
</root>

But I want it saved as this:

<root>
    <child name="first" />
</root>

What do I need to do to accomplish that?

From stackoverflow

• DOM itself does that if there are no child nodes but I don't know why in your case it is doing like this. If you want to do explicitly call Pretty Print on the DOM pointer.

  #include <msxml2.h>
  
  bool FormatDOMDocument (IXMLDOMDocument *pDoc, IStream *pStream)
  {
  
       // Create the writer
       CComPtr <IMXWriter> pMXWriter;
      if (FAILED (pMXWriter.CoCreateInstance(__uuidof (MXXMLWriter), NULL, CLSCTX_ALL)))
      {
          return false;
      }
      CComPtr <ISAXContentHandler> pISAXContentHandler;
      if (FAILED (pMXWriter.QueryInterface(&pISAXContentHandler)))
      {
          return false;
      }
      CComPtr <ISAXErrorHandler> pISAXErrorHandler;
      if (FAILED (pMXWriter.QueryInterface (&pISAXErrorHandler)))
      {
          return false;
      }
      CComPtr <ISAXDTDHandler> pISAXDTDHandler;
      if (FAILED (pMXWriter.QueryInterface (&pISAXDTDHandler)))
      {

     }
  
     // Perform the write
  
     return SUCCEEDED (pMXWriter ->put_output (CComVariant (pStream))) &&
     SUCCEEDED (pSAXReader ->parse (CComVariant (pDoc)));
  }
