• Add this code to the "CMakeLists.txt" file:

find_package(pugixml)
target_link_libraries(hello-pugixml PRIVATE pugixml::pugixml)

• Create a simple XML file with the "users.xml" name inside of the "hello-pugixml/out/build/x64-debug" folder with the following content:

<?xml version="1.0"?>
<people>
  <person>
    <name>Alice</name>
    <age>30</age>
  </person>
  <person>
    <name>Bob</name>
    <age>25</age>

  <person>
    <name>Charlie</name>
    <age>35</age>

    <age>28</age>
  </person>
  <person>
    <name>Eve</name>
    <age>22</age>
  </person>
</people>

• Replace the "hello-pugixml.cpp" file content with this one:

#include <iostream>
#include <fstream>
#include <sstream>
#include <string>
#include <pugixml.hpp>

std::string readFile(const std::string& path)
{
    std::ifstream f(path);
    if (!f.is_open())
    {
        std::cout << "Failed to open the file: " << path << std::endl;
        return "";
    }
    std::stringstream sstr;
    f >> sstr.rdbuf();
    std::string content = sstr.str();
    f.close();
    return content;
}

int main()
{
    // Read the XML-file content
    std::string fileContent = readFile("users.xml");

    // Create the pugi document
    pugi::xml_document doc;

    // Load the XML source
    pugi::xml_parse_result result = doc.load_string(fileContent.c_str());
    if (!result)
    {
        std::cerr << "Parse error: " << result.description() << std::endl;
        return 1;
    }

    // Get names and ages and print them
    auto root = doc.first_child();
    auto people = root.children();
    for (pugi::xml_node person : people)
    {
        std::string name = person.child("name").text().as_string();
        int age = person.child("age").text().as_int();
        std::cout << name << ": " << age << std::endl;
    }

    return 0;
}
