Your friend can't create instances of IXMLDOMElement. What he has to do is to retrieve the document element from the DOM (no VFP7 at hand, but declaration put aside this works with VFP6 also):

* LOCAL oDocument as MSXML2.DOMDocument
* Local oElement as MSXML2.IXMLDOMElement

oDocument = createobject('MSXML2.DOMDocument.3.0')

oDocument.Async = .f.
* retrieve document
oDocument.loadXML("some_document.xml")

oElemProducto = oDocument.documentElement
WITH oElemProducto
  oHolder.cProduct = .getAttributeNode("Code").Text
  ...
