Android jak zidentyfikować audio/wideo z xml?

Question

Pracuję nad czytaniem wiadomości audio i wideo z kanału RSS. Jak mogę się dowiedzieć, czy rss jest dla czytnika wiadomości, audio lub wideo?

To jest kanał wideo: http://feeds.cbsnews.com/CBSNewsVideo i to jest RSS tekst: http://indiatoday.feedsportal.com/c/33614/f/589699/index.rss

Otwierając to możemy zrozumieć, czy to wideo lub tekst. Jak możemy się dowiedzieć, parsując ten plik XML?

     </rss> 

Answer 1

Kanał RSS zawsze zawiera tekst. Ten tekst jest podzielony na kilka kategorii, takich jak tytuł, opis, autor, data publikacji, link itp. Zazwyczaj tekst opisu zawiera całość lub część głównych wiadomości, natomiast tekst linku zawiera adres URL do czytania wiadomości w witryna źródłowa. W przypadku wiadomości CBS tekst linku zawiera odsyłacz do strony na jej stronie, która zawiera film z wiadomościami. Mogli również umieścić wideo osadzone w kodzie HTML tekstu opisu.

Nie ma bezpiecznego sposobu sprawdzenia, czy kanał RSS zawiera wideo, ale możesz wypróbować co najmniej dwie rzeczy (z mojej góry): 1. Przetworzyć kod HTML tekstu opisu, aby zobaczyć, czy istnieje to dowolne osadzone łącza wideo. 2. Pobierz i przeanalizuj kod HTML strony, do której prowadzą linki w tekście linku, aby sprawdzić, czy istnieją odsyłacze do umieszczonych wideo:

Druga opcja będzie działać dla kanału Wiadomości CBS. Istnieje jednak kilka sposobów umieszczenia filmu wideo na stronie HTML i konieczne jest sprawdzenie wszystkich analizatorów przez analizator składni.

Answer 2

Można to zrobić ..

URL url = new URL("http://www.engadget.com/rss.xml"); 
URLConnection conn = url.openConnection(); 
System.out.println("Content-Type:"+conn.getHeaderField("Content-Type")); 

Answer 3

Tak w odniesieniu do wcześniejszych odpowiedzi: Kanały RSS to listy przedmiotów, w opisie przedmiotu znajduje się wyświetlany kod HTML (jest to kod HTML z hasłem emulowanym, bezpiecznie w pliku XML, więc trzeba oczywiście to wychodzę). Z mojej perspektywy można pokazać opis w rodzaju widoku sieciowego. Ale myślę, że to wprowadza problemy z wydajnością. Aby dowiedzieć się, który nośnik zewnętrzny jest ukryty, musisz oczywiście przeanalizować osadzony kod HTML i dojdziesz do utraty kreatywności, po wykonaniu tych linków dojdziesz do strony z osadzonymi multimediami i przy odrobinie szczęścia możesz zadzwonić adres URL wideo z tego (najczęściej jest to jakoś wymieszany afaik)

Jedną z dziwnych rzeczy jest to, że często widzę słowo "zasilacz". Może "Videostreams" jest specyficzną cechą jednego narzędzia lub dostawcy Feedreader?
