Znalazłem poniższy skrypt w sieci. Problem polega na tym: w pliku XML znajdą się jakieś artykuły nawet do tysiąca znaków. Jak zrobić coś takiego żeby pokazywał się tytuł artykułu oraz wstęp jakieś 50-100 znaków. A po kliknięciu w artykuł czy link "więcej", w nowym oknie pokazywałaby się pełna treść artykułu.
