Question

现在我在reddit上调用页面上的所有链接并将其打印出来，但是我可以添加到循环中以仅保留以http://www.reddit.com/r/askcience/开头的链接？

    Document doc; 
    try {


        doc = Jsoup.connect("http://www.reddit.com/r/askscience/search?q=flair%3A%27Psych%27&sort=top&restrict_sr=on").get();


        Elements links = doc.select("a[href]");
        for (Element link : links) {

            System.out.println("\nlink : " + link.attr("href"));

        }

    } catch (IOException e) {
        e.printStackTrace();
    }
}

是的，你得read the docs。

[attr^=valPrefix] elements with an attribute named "attr", and value starting with "valPrefix"

否则，你可以吮吸所有链接，并在字符串上使用正则表达式或startsWith()

jsoup专门解析href
