Qt primarily focuses on providing tools and libraries for GUI development, networking, and other application-level features. While it includes facilities for working with XML through classes like QXmlStreamReader and QXmlStreamWriter, these are more geared toward parsing XML rather than HTML.

For HTML parsing, especially when using XPath expressions, you might need to consider additional libraries or tools. One common choice is to use a third-party library like Gumbo or htmlcxx. These libraries are not part of the Qt framework, but they can be used alongside Qt to handle HTML parsing.

Here's a basic example using htmlcxx for HTML parsing:

#include 
#include 
#include 

int main(int argc, char *argv[]) {
    QCoreApplication a(argc, argv);

    std::string htmlData = "
Hello, world!
";

    htmlcxx::HTML::ParserDom parser;
    tree dom = parser.parseTree(htmlData);

    // Example XPath query
    std::string xpathExpression = "//p/span";
    std::vector::iterator> result;
    htmlcxx::XPath::NodeSet nodeSet;
    htmlcxx::XPath::Parser xpathParser;
    xpathParser.compile(xpathExpression.c_str(), &nodeSet);

    for (tree::iterator it = dom.begin(); it != dom.end(); ++it) {
        nodeSet.evaluate(*it);
        if (nodeSet.size() > 0) {
            result.push_back(it);
        }
    }

    // Output the result
    for (auto &it : result) {
        std::cout << "Match found: " << htmlcxx::HTML::toPlainText(it->begin(), it->end()) << std::endl;
    }

    return a.exec();
}

In this example, I've used htmlcxx for HTML parsing and XPath queries. Note that you need to include the htmlcxx library in your project.

Load testing with Selenium involves simulating a large number of concurrent users to assess how a web application performs under different levels of load. While Selenium itself is primarily designed for functional testing and browser automation, you can use additional tools and frameworks in combination with Selenium to perform load testing. Here are some approaches:

1. Using Selenium Grid with Multiple Nodes:

   • Selenium Grid allows you to distribute test execution across multiple machines, called nodes. You can set up a Selenium Grid with multiple nodes, each running different browser instances.
   • Tools like JMeter or Gatling can be used to simulate concurrent user load and distribute the load across the Selenium Grid.
   • The Selenium Grid setup allows you to scale your load tests by adding more nodes.

2. Combining Selenium with JMeter:

   • JMeter is a popular open-source load testing tool. While JMeter is not designed for browser automation, you can use it to simulate user interactions at the HTTP protocol level.
   • Record user scenarios with JMeter's HTTP(S) Test Script Recorder while performing actions in the browser. Convert recorded scenarios to JMeter test plans.
   • Run the JMeter test plans to simulate concurrent users, and monitor the performance of your web application.

3. Using Headless Browsers:

   • Headless browsers (browsers without a graphical user interface) can be used to simulate user interactions without the overhead of rendering pages.
   • Tools like Selenium with headless Chrome or headless Firefox can be used for load testing. Run multiple instances of headless browsers simultaneously to simulate concurrent users.

4. Combining Selenium with Gatling:

   • Gatling is another popular open-source load testing tool that is scriptable in Scala.
   • You can write Gatling scripts to simulate user scenarios using the Selenium DSL (Domain Specific Language) provided by Gatling.
   • Gatling can be used to generate a high load on your web application and measure performance metrics.

5. Using Cloud-Based Load Testing Services:

   • Cloud-based load testing services like BlazeMeter, Flood Element, or BrowserStack can be used for Selenium-based load testing.
   • These services provide scalable infrastructure for running Selenium tests in parallel to simulate a large number of concurrent users.

6. Custom Solutions with WebDriver:

   • You can write custom scripts using Selenium WebDriver to simulate user interactions and run them concurrently using a scripting or programming language (e.g., Python, Java, etc.).
   • Implement logic to run multiple threads or processes, each simulating a user. Be cautious about the limitations and synchronization issues that may arise in a multithreaded environment.

When performing load testing with Selenium, consider the following:

• Monitor the performance of your web application to identify bottlenecks.
• Be mindful of the limitations of the testing environment, especially when running tests on local machines.
• Ensure that your load testing approach aligns with your specific testing goals and requirements.

Using a proxy server to change your IP address allows you to access websites or services that may be restricted based on your current IP. To use a proxy server to change your IP address, follow these steps:

1. Find a reliable proxy server: Look for a reputable proxy server list or website that provides proxy servers. Be cautious when choosing a proxy server, as some may be unreliable, slow, or pose security risks.

2. Choose a proxy server: Select a proxy server from the list that meets your needs in terms of location, speed, and reliability.

3. Configure your browser or software: Open your web browser or software and navigate to the proxy settings. Configure the settings to use the proxy server you've chosen. For web browsers, this is usually found in the settings or preferences menu.

4. Test the connection: Visit a website that displays your IP address or use an IP checker tool to ensure that the proxy server is working correctly and has successfully changed your IP address.

5. Use the proxy server: With the proxy server configured, you can now use the internet with the new IP address provided by the proxy server. Keep in mind that using proxies can slow down your internet connection, so be patient when browsing or accessing content.

You cannot use a proxy server in Outlook (for security reasons). Therefore, it is possible to organize a local proxy with traffic forwarding through the port. Or you can use third-party tools such as ProxyCap.

When choosing a proxy through which to connect to Skype, pay attention to the stability of its work, the level of anonymity and low load that exceeds the final speed of the connection. Launch the Skype application and open the context menu "Tools". Through the "Advanced" tab, go to "Connection" to open the "Change settings" tab. Here, in the special form, specify the IP address and port, and then click "Save" and restart Skype.
