Try this, I found this years ago on the web.

#include 

bool FormatDOMDocument (IXMLDOMDocument *pDoc, IStream *pStream)
{

    // Create the writer

    CComPtr  pMXWriter;
    if (FAILED (pMXWriter.CoCreateInstance(__uuidof (MXXMLWriter), NULL, CLSCTX_ALL)))
    {
        return false;
    }
    CComPtr  pISAXContentHandler;
    if (FAILED (pMXWriter.QueryInterface(&pISAXContentHandler)))
    {
        return false;
    }
    CComPtr  pISAXErrorHandler;
    if (FAILED (pMXWriter.QueryInterface (&pISAXErrorHandler)))
    {
        return false;
    }
    CComPtr  pISAXDTDHandler;
    if (FAILED (pMXWriter.QueryInterface (&pISAXDTDHandler)))
    {
        return false;
    }

    if (FAILED (pMXWriter ->put_omitXMLDeclaration (VARIANT_FALSE)) ||
        FAILED (pMXWriter ->put_standalone (VARIANT_TRUE)) ||
        FAILED (pMXWriter ->put_indent (VARIANT_TRUE)) ||
        FAILED (pMXWriter ->put_encoding (L"UTF-8")))
    {
        return false;
    }

    // Create the SAX reader

    CComPtr  pSAXReader;
    if (FAILED (pSAXReader.CoCreateInstance (__uuidof (SAXXMLReader), NULL, CLSCTX_ALL)))
    {
        return false;
    }

    if (FAILED (pSAXReader ->putContentHandler (pISAXContentHandler)) ||
        FAILED (pSAXReader ->putDTDHandler (pISAXDTDHandler)) ||
        FAILED (pSAXReader ->putErrorHandler (pISAXErrorHandler)) ||
        FAILED (pSAXReader ->putProperty (
        L"http://xml.org/sax/properties/lexical-handler", CComVariant (pMXWriter))) ||
        FAILED (pSAXReader ->putProperty (
        L"http://xml.org/sax/properties/declaration-handler", CComVariant (pMXWriter))))
    {
        return false;
    }

    // Perform the write

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