Merhaba
yeni başlayan biri olarak rss okuyan bir uygulama yapmak için kıvranıyorum. http://rss.hurriyet.com.tr/rss.aspx?sectionId=1
bu adresteki xml dosyasının içinde description düğümlerinde html tagları var . Tamamı value olarak alamıyorum.
Değer olarak geriye "<" dönderiyor . ilk karaker bu . sonrasını görmüyor. bu özel kararterleri görmezden gelmesini nasıl sağlarım?
Teşekkürler
