Use DOM_Document::importNode() to transfer nodes from one document to
another.
You'd get something like:
// Find oldChild in doc1
DOM_Element oldCreationInformationElem =
mp7->findElementByName("CreationInformation", 0);
// Find newChild in doc2
DOM_Element newCreationInformationElem =
mp7LabelObj->findElementByName("CreationInformation", 0);
// Import node
DOM_Node imported =
audioVisualElem.getOwnerDocument().importNode(newCreationInformationElem);
// replace oldCreationInformationElem
audioVisualElem.replaceChild(imported,
oldCreationInformationElem);
