Question

以下是我编写的代码段：

String url = "https://www.premierleague.com/tables";

doc = Jsoup.connect(url).get();
table = doc.select("table").first();

rank = table.select("td[id=tooltip]").iterator(); //Position
team = table.select("td[class=team]").iterator(); //Club
points = table.select("td[class=points]").iterator(); //Points

我可以获取位置，俱乐部和积分等数据，因为我可以用类名或ID识别它们，但我无法获取其他数据，如Played，Won，Draw，Loss，GF，GA，GD等

有人可以帮助我吗？

您可以根据结构使用选择器，请参阅此示例，以获取 won 列中的第一个条目：http://try.jsoup.org/~camnKp8NJYL0meyfIRXEtV8E5B4

要使选择器正确，您可以使用Google Chrome中的开发者工具（f12），右键单击“元素”标签中的元素，然后选择Copy -> Copy selector。

Iterator<Element> gamesPlayed = table.select("tbody tr > td:nth-child(4)").iterator();
Iterator<Element> gamesWon = table.select("tbody tr > td:nth-child(5)").iterator();
Iterator<Element> gamesDrawn = table.select("tbody tr > td:nth-child(6)").iterator();
Iterator<Element> gamesLost = table.select("tbody tr > td:nth-child(7)").iterator();

或者逐行解析表并存储单元格值，如下例所示：

示例代码

String userAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Safari/537.36";
String url = "https://www.premierleague.com/tables";

Document doc;
String position, club, played, won;

try {
    doc = Jsoup.connect(url).userAgent(userAgent).get();

    Element table = doc.select("table").first();

    for (Element row : table.select("tr")) {

        Elements cells = row.select("td");

        if(cells.size()<5) continue;

        position = cells.get(1).select(".value").first().text();
        club = cells.get(2).select(".long").first().text();
        played = cells.get(3).text();
        won = cells.get(4).text();

        System.out.println(position + " " + " " + club + "\n\tplayed: " + played + " won: " + won);

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

<强>输出

1  Chelsea
    played: 21 won: 17
2  Arsenal
    played: 22 won: 14
3  Tottenham Hotspur
    played: 22 won: 13
4  Liverpool
    played: 22 won: 13
5  Manchester City
    played: 22 won: 13
...

无法使用Jsoup从表中获取特定数据
