Napisałem sobie taką oto klasę:

Po wywołaniu tej klasy, przypisuję do każdej zmiennej szukanej wartości - zdjęcie, tytuł i treść.

Niestety tytuł zawiera również ciąg URL obrazka, natomiast tekst zawiera dodatkowo obrazek oraz tytuł. Gdzie robię błąd? Jak to oddzielić?

Jednocześnie proszę o sugestię co mogę poprawić w samej klasie.
