Getting node values separately using msxml parser in vc++?

In the below example how can i get the text values separately like :
       {
         {i am parent text},
         {i am child1},
         {i am child2},
         {with above childs}
       }
       using {get_nodeValue} property in MSXML using c++ :
       {<rootElement>}
         {<parent>i am parent text}
            {<child_1>i am child1</child_1>}
            {<child_2>i am child2</child_2>}
         {with above childs}
         {</parent>}
       {</rootElement>}
       here when i am using {get_nodeValue()} for the {parent} element, i am getting null as it is of
        NODE_ELEMENT type.
        i have referred following link :
<https://docs.microsoft.com/en-us/previous-versions/windows/desktop/ms756022(v%3Dvs.85)>
Here is the code used:
ParseCurrentNode(IXMLDOMNode* CurrentNode)
{
   VARIANT nValNode;
   BSTR bstrNodeText;
   CString strNodeText;
   Nodevalue->get_text(&bstrNodeText);
   strNodeText = bstrNodeText;
   SysFreeString(bstrNodeText);
   HRESULT temphr=FormatNode->get_nodeValue(&nValNode);
}

result is:
strNodeText  (concatenated string)="i am parent text i am child1 i am child2 with above childs"
nValNode = null;

Here CurrentNode is "parent":<rootelement><parent>i am parent text<child1>i am child 1</child1><child2>i am child 2</child2>
with above childs
</rootelement>
