[Renato Tegon Forti]

Hi All, I trying copy node of documents, but I receive erro. Can anyone help-me:   See my code:               xercesc_2_6::DOMDocument* pDocThegiver = m_pThegiverParser->getDocument();             DOMElement* pRootThegiver = pDocThegiver->getDocumentElement();               xercesc_2_6::DOMDocument* pDocReceptor = m_pReceptorParser->getDocument();             DOMElement* pRootReceptor = pDocReceptor->getDocumentElement();                     DOMNodeList* pNodeList = pRootThegiver->getChildNodes();               for ( int i = 0 ; i <= (int)pNodeList->getLength() ; i++ )             {                   DOMNode* pNode = pNodeList->item(i);                     if(pNode != NULL)                   {                         CString strNodeName = pNode->getNodeName();                         if(strNodeName == "product")                         {                              pRootReceptor->appendChild(productElem); // here, I receive error. Why?                         }                   }             }   Node that I try copy         <product>             <productcontrol>                   <id>{E5BF529A-9E34-4133-9035-7E5E903ADA46}</id>                   <mdlid>{E5BF529A-9E34-4133-9035-7E5E903ADA45}</mdlid>             </productcontrol>                   <generalinfo>                   <productname>Put your product name here.</productname>                   <projectdescription>Put your project description here.</projectdescription>                   <detailedprojectdescription>Put your detailed project description here.</detailedprojectdescription>                   <maxquantity>0</maxquantity>                   <difficulty>00,00</difficulty>             </generalinfo>                         <rawmaterials>                   <rawmaterial>                         <id>{E5BF529A-9E34-4133-9035-7E5E903ADA49}</id>                         <quantity>0</quantity>                   </rawmaterial>             </rawmaterials>       </product>   Thaks
