java - 无法从 HTML 字符串格式读取 Src 属性

Question

我有一个字符串如下

<iframe class = 'sproutvideo-player' src = '//videos.sproutvideo.com/embed/1c9adbb11d18e3c994/a5fd279ead76557c' width = '630' height = '354' frameborder = '0' allowfullscreen > < /iframe>

我正在尝试从中读取属性 src 。

我尝试过如下

String html = "<iframe class = 'sproutvideo-player' src = '//videos.sproutvideo.com/embed/1c9adbb11d18e3c994/a5fd279ead76557c' width = '630' height = '354' frameborder = '0' allowfullscreen > < /iframe>";

    Document doc = Jsoup.parse(html);

    Elements links = doc.select("src");

         System.out.println(links.attr("src"));

您能告诉我如何读取 src 属性吗？

Answer 1

改变

 Elements links = doc.select("src");

至

 Elements links = doc.select("iframe");
