Below function will read complete xml with node and values,

xmlDocPtr pFilePointer = xmlParseFile(xmlFile);
xmlNodePtr pNodePointer = xmlDocGetRootElement(pFilePointer);

void readXML(const xmlDocPtr cpFilePointer, const xmlNodePtr cpNodePointer) {
    string value;
    xmlDocPtr pFilePointer = cpFilePointer;
    xmlNodePtr pNodePointer = cpNodePointer;
    while (pNodePointer != NULL) {
        if (NULL != pNodePointer->xmlChildrenNode) {
            xmlNodePtr pParentPointer = pNodePointer;
            string node = (const char *)pParentPointer->name;
            pNodePointer = pNodePointer->xmlChildrenNode;
            if (!xmlStrcmp(pNodePointer->name, (const xmlChar *)"text")) {
                xmlNodeListGetStringWrapper(pFilePointer, pNodePointer, value);
                cout << node << ":" << value << endl;
            } else {
                LOG2((TEXT("no need to read node %s\n"), pParentPointer->name));
            }
        } else if (NULL != pNodePointer->next) {
            pNodePointer = pNodePointer->next;
        } else {
            pNodePointer = pNodePointer->parent;
            pNodePointer = pNodePointer->next;
        }
    }
}
