Au fait ma deuxieme alternative que j avais trouvé est la suivante, mais lorsque au lieu de faire
iXMLDoc->loadXML(CComBSTR(src),&bSuccess); je fait le iXMLDoc->load(CComVariant(url),&bSuccess); avec comme url "config.xml" ca me sort n importe quoi, il ne le lis pas comme il faut apparement!
Encore merci pour votre aide
