How to use libadblockplus?

[Alecyrus]

I really need someone who can help me that will be very grateful.
I had read carefully the source code of Abpshell (The demo application in the libadblock program), but I didn't know how to use matches() fucton and GetElementHidingSelectors() function. I even don't know what documentUrls is , How I get the documentUrl.
The application I develop is advertisement Identifier that can split the ad html section and ad urls from target page. I will be very thankful if someone can offer me some suggestions.

Environment

mac OS X 10.13
XCode 9.3

The latest version of libadblockpuls from Github.

How to reproduce

My code:

int main(int argc, const char * argv[]) {
    std::cout << "Initialize the JS engine...";
    AdblockPlus::AppInfo appInfo;
    appInfo.version = "1.0";
    appInfo.name = "abpshell";
    appInfo.application = "standalone";
    appInfo.applicationVersion = "1.0";
    appInfo.locale = "en-US";

    auto platform = AdblockPlus::DefaultPlatformBuilder().CreatePlatform();
    platform->SetUpJsEngine(appInfo);
    auto& filterEngine = platform->GetFilterEngine();
    std::cout << "success\n";

    
    Subscription subscription = filterEngine.GetSubscription("https://easylist-downloads.adblockplus.org/easylist.txt");
    subscription.AddToList();
    if (subscription.IsListed()) {
        std::cout << "Imported successfully!\n";
    }
    subscription.UpdateFilters();
    
    cout<<"\nSubscription::\n";
    ShowSubscriptionList(filterEngine.GetListedSubscriptions());
    
    cout<<endl<<"AAURL:"<<filterEngine.GetAAUrl();

    if(filterEngine.IsAAEnabled ()) std::cout << " ...AA enabled!\n";
    else {
        filterEngine.SetAAEnabled(true);
        if(filterEngine.IsAAEnabled ()) std::cout << " AA renabled!\n\n";
    }
    
    cout<<"Test element selector:";
    std::vector<std::string> selectors = filterEngine.GetElementHidingSelectors("google.ru");
    
    cout<<"The number of selectors: "<<selectors.size()<<endl<<endl;
    
    for (auto it = selectors.begin();
         it != selectors.end(); it++)
        std::cout <<*it<< std::endl;
    
    
    
    cout<<endl<<"Test request:";
    filterEngine.GetFilter("adbanner.gif").AddToList();
    FilterPtr match_1 = filterEngine.Matches("http://example.org/adbanner.gif", AdblockPlus::FilterEngine::CONTENT_TYPE_IMAGE, "");
    if (!match_1){
        std::cout << "No match" << std::endl;}
    else if (match_1->GetType() == AdblockPlus::Filter::TYPE_EXCEPTION)
        std::cout << "Whitelisted by " << match_1->GetProperty("text").AsString() << std::endl;
    else
    {std::cout << "Blocked by " << match_1->GetProperty("text").AsString() << std::endl;}
    
    cout<<endl<<"Test element hiding:";
    FilterPtr match = filterEngine.Matches("http://simple-adblock.com/adblocktest/files/elementhide.html", AdblockPlus::FilterEngine::CONTENT_TYPE_ELEMHIDE, "");

    if (!match){
        std::cout << "No match" << std::endl;}
    else if (match->GetType() == AdblockPlus::Filter::TYPE_EXCEPTION)
        std::cout << "Whitelisted by " << match->GetProperty("text").AsString() << std::endl;
    else
    {std::cout << "Blocked by " << match->GetProperty("text").AsString() << std::endl;}
  
    
    return 0;
}

Expected behaviour

How to reproduce
disable AA exceptions subscription (the link above)
invoke filterEngine.getElementHidingSelectors(..) for "google.ru" and get 17387 selectors. make sure ads is NOT shown for "iphone 6 plus" request in google.ru
enable AA by adding subscription (the link above)
invoke filterEngine.getElementHidingSelectors(..) for "google.ru" and get 17388 selectors. make sure ads is NOT shown for the request above.

The number of selectors shouldn't be zero..
