我正在使用Jaunt API抓取新聞標題和此供稿中的鏈接。

            agent.visit("http://timesofindia.feedsportal.com/c/33039/f/533916/index.rss");
            Elements items=agent.doc.findEach("<item>");
            for(Element item:items)
            {
                headline=item.findFirst("<title>").getText();
                link=item.findFirst("<link>").getText();
                System.out.println("headline:"+headline+"\nlink:"+link+"\n");
            }

現在我獲得了所有的頭條新聞，但鏈接為空!!!!當我刮另外一個報紙訂閱源時，發生了同樣的事情。那個鏈接節點是否有任何特殊的東西（編碼）給出了null或我做錯了什么。

Answer 1

我不確定，但是findFirst可能不處理<link>因為findFirst更面向注釋。 帶有適當查詢的getFirst是否可行？
