VC++ create XML file but can not find method "appendChild()"

Question

I'm using vs2015/vc++ to generate a XML document.I follow a example from Microsoft document. First of all, I add this:

import "msxml6.dll"
using namespace MSXML2;*

Then in the main loop I add such codes:

HRESULT hr = pXMLDom.CreateInstance(__uuidof(MSXML2::DOMDocument60), NULL,     CLSCTX_INPROC_SERVER);

if (FAILED(hr))
{
    printf("Failed to instantiate an XML DOM.\n");
    return;
}

try
{
    pXMLDom->async = VARIANT_FALSE;
    pXMLDom->validateOnParse = VARIANT_FALSE;
    pXMLDom->resolveExternals = VARIANT_FALSE;
    pXMLDom->preserveWhiteSpace = VARIANT_TRUE;

    // Create a processing instruction targeted for xml.
    MSXML2::IXMLDOMProcessingInstructionPtr pi =       pXMLDom->createProcessingInstruction(L"xml", L"version='1.0'");    
    pXMLDom->appendChild(pi);

    // Create a comment for the document.
    MSXML2::IXMLDOMCommentPtr pc = pXMLDom->createComment(L"sample xml file created using XML DOM object.");
    pXMLDom->appendChild(pc);

...... }

But the VS2015 always told me that class "MSXML2::IXMLDOMDocument" has no member "appendChild". Also I could not compile it. I google a lot but could not find the answer. Does anyone know the reason? Thank you.

You can try something like this

    static_cast<MSXML2::IXMLDOMNodePtr>(pXMLDom)->appendChild(pi);

I had the same problem and worked for me
