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.

When scraping paginated content, fetching the "next page" usually involves extracting the URL of the next page from the HTML of the current page. In PHP, you can use a library like Simple HTML DOM Parser to parse HTML and extract the URL for the next page.

Here's an example of how you might scrape the next page URL using PHP

Install Simple HTML DOM Parser:

You can download it from sourceforge and include it in your project, or use Composer:

composer require sunra/php-simple-html-dom-parser

Write a PHP script to scrape the next page URL:

find('a.next-page-link', 0);

    if ($nextPageLink) {
        // Extract the href attribute (URL) from the link
        $nextPageUrl = $nextPageLink->href;
        return $nextPageUrl;
    } else {
        return null; // No next page link found
    }
}

// Example usage
$currentUrl = 'https://example.com/page1'; // Replace with the URL of the current page
$nextPageUrl = scrapeNextPageUrl($currentUrl);

if ($nextPageUrl) {
    echo "Next Page URL: $nextPageUrl";
} else {
    echo "No Next Page URL found.";
}

Replace the $currentUrl variable with the URL of the current page.

Adjust the HTML element selector ('a.next-page-link') based on the structure of the website you are scraping.

Run the script:

Execute the PHP script to see the URL of the next page.

It means a proxy server for devices that connect to the router via WiFi. It is also a remote server to let traffic through. For example, a user sends a request to Netflix from his smartphone through a proxy that is hosted in the UK. Netflix servers will "recognize" such a user as being from the UK (regardless of his actual location).

Shared proxies should be understood as IPs and port numbers available to everyone. That is, many users can use them simultaneously. The most unreliable and slowest option.

In the messenger settings, go to "Data and Drive". Click on "Proxy settings", and then, enabling the "Use proxy settings" tab, enter the server, port, username and password in the specially highlighted fields. If you are going to make settings in the Desktop version, you will need to go to the menu. There, in the "Connection method" item, click on "TSP via Socks5" and enter the required data.
