int main()
{
    // Create an instance of the API client
    std::shared_ptr apiClient =
        std::make_shared();
    apiClient->setAppKey(L"APP_KEY");
    apiClient->setAppSid(L"APP_SID");
    apiClient->setBaseUrl(L"https://api.aspose.cloud");

    // Create a conversion request
    std::shared_ptr request =
        std::make_shared();
    request->setSourceUrl(L"https://example.com/input.html");
    request->setFormat(L"pdf");

    try
    {
        // Convert HTML to PDF
        std::shared_ptr result =
            apiClient->getHTMLApi()->postConvertDocument(request);

        // Download the converted PDF file
        apiClient->downloadFile(result->getPdf()->getHref(), L"output.pdf");

        std::cout << "HTML to PDF conversion successful." << std::endl;
    }
    catch (std::exception& ex)
    {
        std::cout << "Error: " << ex.what() << std::endl;
    }

    return 0;
}

Extract HTML Fragment via C++ Cloud API

Aspose.HTML Cloud SDK for C++ has included complete support for extracting a particular sections or fragments of an HTML documents inside cloud-based C++ applications. This feature is very useful when dealing with large HTML files and needing to retrieve only a portion of the content for further processing or display. The SDK also supports extracting structured data from HTML documents using XPath queries or CSS selectors. This functionality proves valuable when working with web scraping, data mining, or content extraction tasks. The following code example demonstrates how to extract a specific sections or fragments from HTML documents using the C++ SDK.

#include 
#include 
#include 

using namespace std;
using namespace aspose::html::cloud::api;
using namespace aspose::html::cloud::model;

int main() {
    // Configure Aspose.HTML Cloud credentials
    aspose::html::cloud::AsposeHtmlCloudConfig config;
    config.set_client_id("your_client_id");
    config.set_client_secret("your_client_secret");

    // Create an instance of the HTMLApi
    aspose::html::cloud::api::HTMLApi htmlApi(config);

    // Set the source HTML file for extraction
    std::string name = "sample.html";
    std::string folder = "html_folder";

    // Set the CSS selector for the HTML fragment to be extracted
    std::string selector = "#myFragment";

    try {
        // Extract the HTML fragment
        std::shared_ptr response = htmlApi.getHtmlFragmentByCSSSelector(name, folder, selector);

        // Save the extracted HTML fragment to a file
        std::ofstream outputFile("output.html");
        outputFile << response->getFragmentContent();
        outputFile.close();

        std::cout << "HTML fragment extracted successfully." << std::endl;
    } catch (const aspose::html::cloud::ApiClientException& ex) {
        std::cout << "Error occurred: " << ex.get_message() << std::endl;
    }

    return 0;
}
