Add indent spaces to xml nodes with ms IXMLDOM

Question

Hi All,
  Currently I was update a xml file with IXMLDOM, after add nodes to xml file, we found the new added node was written in one line always.  this make it hard to find the differences with merge tools.
  and after we try to add text node to the xml to format it, it works unless we added nested nodes, it looks like:
<RootNode>
<ChildNodes>
<Child>value</Child></ChildNodes></RootNode>
Ugly, huh
And, when we set node's type with IXMLDOMNode::put_dataType it makes the node like:
<Name xmlns:dt="urn:schemas-microsoft-com:datatypes" dt:dt="string" Encoding="Standard" >Connections</Name>
but, the original nodes was: 
<Name dt:dt="string" Encoding="Standard" xmlns:dt="urn:schemas-microsoft-com:datatypes">Connections</Name>
Also, it will not affect the its function, just cause extra efforts to merge the results.
So my questions:
   1. is there any built-in functions that can be used to format the xml file to a indented version. 
   2. how to adjust the sequences of attributes of a node.
Thanks, 
Levi
PS: currently, I was working on Windows CE 6.0, and these issues met on desktop OS too.

I used to use this code in a previous version of a project. I don't
know if CE 6 will support it though.
static bool FormatDOMDocument( MSXML2::IXMLDOMDocument *pDoc )
    // 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)))
        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 <ISAXXMLReader> pSAXReader;
    if (FAILED(pSAXReader.CoCreateInstance(__uuidof

        return false;
    if (FAILED(pSAXReader->putContentHandler
(pISAXContentHandler)) ||
        FAILED(pSAXReader->putDTDHandler (pISAXDTDHandler)) ||
        FAILED(pSAXReader->putErrorHandler

        FAILED(pSAXReader->putProperty(
reinterpret_cast<unsigned short*>(

(pMXWriter))) ||
        FAILED(pSAXReader->putProperty(
reinterpret_cast<unsigned short*>(
L"http://xml.org/sax/properties/declaration-handler" ), CComVariant
(pMXWriter))))
        return false;
    // Perform the write
    bool success1 = SUCCEEDED( pMXWriter->put_output(
CComVariant(pDoc ) ) );
    bool success2 = SUCCEEDED( pSAXReader->parse( CComVariant(
pDoc ) ) );
    return success1 && success2;
