从 jsoup 的嵌套 href 中检索数据

Question

我想从 jsoup 的嵌套 href 中检索数据，我的意思是：我有 href: https://www.sherdog.com/news/rankings/2/Sherdogs-Official-Mixed-Martial-Arts-Rankings-164999

我想从这 10 名战士中获取每个数据，例如：

1。菌种年龄：37 要么协会：强势格斗队伍

2。丹尼尔科米尔年龄：40 要么协会：美国跆拳道学院

等..

如何操作？

    String url = "https://www.sherdog.com/news/rankings/2/Sherdogs-Official-Mixed-Martial-Arts-Rankings-164999";
    Document document = Jsoup.connect(url).get();

    Elements allH1 = document.select("h2");
    for (Element href : allH1) {

        Elements allAge = document.select("div.birth_info");
        for (Element  age : allAge) {
            System.out.println(href.select("a[href]").text().toString());
            System.out.println(age.select() // something there?);
        }

您要查找的数据存在于不同的页面上 - 每个战士都有自己的页面，因此您必须一个接一个地抓取所有页面才能获取数据。
首先你必须得到每个页面的link，选择器h2 > a[href]：

String url = "https://www.sherdog.com/news/rankings/2/Sherdogs-Official-Mixed-Martial-Arts-Rankings-164999";
Document document = Jsoup.connect(url).get();
Elements fighters = document.select("h2 > a[href]");
for (Element fighter : fighters) {
     System.out.println(fighter.text() + " " + fighter.attr("href"));
}

之后，您可以加载每个页面并提取数据：

String fighterUrl = "https://www.sherdog.com" + fighter.attr("href"); 
Document doc = Jsoup.connect(fighterUrl).get();
Element fighterData = doc.select("div.data").first();
System.out.println(fighterData.text());

结合起来，你得到：

String url = "https://www.sherdog.com/news/rankings/2/Sherdogs-Official-Mixed-Martial-Arts-Rankings-164999";
Document document = Jsoup.connect(url).get();
Elements fighters = document.select("h2 > a[href]");
for (Element fighter : fighters) {
    System.out.println(fighter.text());
    String fighterUrl = "https://www.sherdog.com" + fighter.attr("href"); 
    Document doc = Jsoup.connect(fighterUrl).get();
    Element fighterData = doc.select("div.data").first();
    System.out.println(fighterData.text());
    System.out.println("---------------");
}

并且（部分）输出是：

Stipe Miocic Born: 1982-08-19 AGE: 37 Independence, Ohio United States Height 6'4" 193.04 cm Weight 245 lbs 111.13 kg Association: Strong Style Fight Team Class: Heavyweight Wins 19 15 KO/TKO (79%) 0 SUBMISSIONS (0%) 4 DECISIONS (21%) Losses 3 2 KO/TKO (67%) 0 SUBMISSIONS (0%) 1 DECISIONS (33%)

Daniel Cormier Born: 1979-03-20 AGE: 40 San Jose, California United States Height 5'11" 180.34 cm Weight 251 lbs 113.85 kg Association: American Kickboxing Academy Class: Heavyweight Wins 22 10 KO/TKO (45%) 5 SUBMISSIONS (23%) 7 DECISIONS (32%) Losses 2 1 KO/TKO (50%) 0 SUBMISSIONS (0%) 1 DECISIONS (50%) N/C 1

如果您想获取年龄、关联等作为单独的字段，则必须使用正则表达式提取它们。
