Java 如何在新行上打印每一条信息

您好，代码运行良好，但我想知道是否有一种方法，我可以让它打印后，在一个新的行上的某个点刮的信息。对于这段代码，我希望每个公司的信息都打印在新的一行上。下面列出了代码设置为刮取的站点。非常感谢你的帮助和阅读。

您的问题是将整个表体作为一个元素。您可以通过执行以下操作来解决此问题：

  Elements body = document.select("div#scr-res-table tbody tr");

然后，下面的代码应该在单独的行上打印每个表行

  for(Element p : body) {
    System.out.println(p.text());
  }

我根据你的代码创建了一个原型

    public static void main(String[] args) {
    System.out.println(new App().getGreeting());
    print("running...");
    Document document;
    try {
        document = Jsoup.connect("https://finance.yahoo.com/most-active").get();
        Elements body = document.select("div#scr-res-table tbody");

        String title = document.title();
        print("  Title: " + title);
        String table = printTable(body.first()); //<---remember to select the first found of the table body.
        print(table);

    } catch (IOException e) {
        e.printStackTrace();
    }
    print("done");
}

public static void print(String string) {
    System.out.println(string);
}
/**
 * Extract data fields from each row <tr>....</tr>
 */
public static String printLine(Element row) {
    //Each <td> cell has different content, you need to look at the 
    //html source and extract them individually, here I extract 3 of them as example

    String symbol = row.select("td[aria-label='Symbol'] a").first().text();
    String name = row.select("td[aria-label='Name']").first().text();
    String volume = row.select("td[aria-label='Volume'] span").first().text();
    return symbol + " " + name + " " + volume;
}

/**
 * Take in a <tbody> tree, and print the every row inside as a string.
 */
public static String printTable(Element tableBody){
    StringBuffer sb = new StringBuffer();
    Elements allRows = tableBody.select("tbody").first().children();
    for(Element row : allRows){
        String rowString = printLine(row);
        sb.append(rowString).append(System.lineSeparator());
    }
    return sb.toString();
}

您需要在以后添加自己的格式。

如果您发布一个要拆分的文本示例，这会有所帮助。通用电气公司5.79-0.21-3.50%234.597M 108.097M 50.646B十亿美元/A:美国银行股份有限公司20.87-1.00-4.57%110.266M91.593M181.06B8.48:：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：：像这样的话，前两行将分开打印，而不是像一堆文本，我只是使用了：把队伍分成两半，这很有帮助。我对编码比较新，所以谢谢你的支持。它能回答你的问题吗？
