XmlNode* parentNode = new XmlNode("parent"); XmlNode* childNode = new XmlNode("child", "value"); parentNode->addChildNode(childNode); XmlAttributes* attributes = new XmlAttributes(); attributes->addAttribute("attribute1", "value1"); attributes->addAttribute("attribute2", "value2"); childNode->setAttributes(attributes); XmlNode* firstAttribute = childNode->firstAttribute(); XmlValue* attributeValue = firstAttribute->getValue(); std::cout << attributeValue->toString() << std::endl;
XmlNode* rootNode = new XmlNode("root"); XmlAttributes* attributes = rootNode->getAttributes(); XmlNode* firstAttribute = rootNode->firstAttribute(); if (attributes == nullptr) { std::cout << "The root node has no attributes." << std::endl; } else { std::cout << "The root node has attributes." << std::endl; } if (firstAttribute == nullptr) { std::cout << "The root node has no first attribute." << std::endl; } else { std::cout << "The root node's first attribute is: " << firstAttribute->getName() << " with value " << firstAttribute->getValue()->toString() << std::endl; }In this example, we create a root node with no attributes and try to get its first attribute. We then print whether the node has attributes and whether it has a first attribute. This code could be used in an XML manipulation library.
