      <link rel="icon" href="//s.ytimg.com/yts/img/favicon_32-vfl8NGn4k.png" sizes="32x32">
      <link rel="icon" href="//s.ytimg.com/yts/img/favicon_48-vfl1s0rGh.png" sizes="48x48">
      <link rel="icon" href="//s.ytimg.com/yts/img/favicon_96-vfldSA3ca.png" sizes="96x96">
      <link rel="icon" href="//s.ytimg.com/yts/img/favicon_144-vflWmzoXw.png" sizes="144x144">

Answer 1

如果您想获得所有href值：

List<String> href = new ArrayList<>();
// Considering that text is a String variable that contains the html
final Document document = Jsoup.parse(text);
for (Element element : document.select("link")) {
    href.add(element.attr("href"));
}
// In this point the list href will have all the links

如果您只需要选择具有特定rel属性的链接，则可以切换＆＃34; link＆＃34;由：

"link[rel~=\"icon\"]" //could have 1 or more rel values
"link[rel=\"icon\"]" //rel equals to icon
