#includeThis code loads an XML file called "example.xml" and gets the first child element of the root element. It then prints the name of the first child element, which should be "element1". The package library used in this example is TinyXML2, which is a lightweight XML parsing library for C++.#include "tinyxml2.h" using namespace std; using namespace tinyxml2; int main() { XMLDocument doc; doc.LoadFile("example.xml"); // Get the root element XMLElement* root = doc.FirstChildElement("document"); // Get the first child element XMLElement* child = root->FirstChildElement(); // Print the name of the first child element cout << "First child element: " << child->Name() << endl; return 0; }
