我想解析每个单元格的数据，以"Montag"(星期一)下的所有5个单元格为例.我尝试了几种使用JSOUP解析此网站的方法，但是我没有获得任何成功.我的主要目标是在Android应用程序的列表视图中显示内容.现在，我尝试在Java控制台中打印内容.两种语言都可以接受:).感谢您的帮助.

I want to parse the data for each cell, all 5 cells under "Montag"(Monday) as an example.I tried several ways of parsing this Website using JSOUP but i havent got any succes with it.

推荐答案

以下是您需要遵循的步骤:

Here are the steps you would need to follow:

1)您可以使用以下任何Java库进行HTML抓取:

• 标签汤
• HtmlUnit
• 网络收获
• jARVEST
• jsoup
• Jericho HTML解析器

1) You could use any of the below java libraries for HTML scraping:

• Tag Soup
• HtmlUnit
• Web-Harvest
• jARVEST
• jsoup
• Jericho HTML Parser

2)使用 Xpath助手

例如1:在查询中输入"//tr[1]//td[1]"，它将给出所有表元素在位置(1,1)

Eg 1: Enter "//tr[1]//td[1]" in the query and it will give all table elements at position (1,1)

例如2:"/html/body[@class='tt']/center/table[1]/tbody/tr[4]/td[3]/table/tbody/tr/td"将为您提供Montag下的所有15个值.

Eg 2: "/html/body[@class='tt']/center/table[1]/tbody/tr[4]/td[3]/table/tbody/tr/td"Will give you all 15 values under Montag.

例如3:"/html/body[@class='tt']/center/table[1]/tbody/tr/td/table/tbody/tr/td"将为您提供该表的所有380个条目

Eg 3: "/html/body[@class='tt']/center/table[1]/tbody/tr/td/table/tbody/tr/td"Will give you all 380 entries of the table

OR

使用 Jsoup

import org.jsoup.Jsoup;
import java.io.IOException;

public class Main {
    public static void main(String[] args) throws IOException {
        org.jsoup.nodes.Document doc = Jsoup.connect("http://www.kantschule-falkensee.de/uploads/dmiadgspahw/klassen/A_Klasse_11.htm").get();
        org.jsoup.select.Elements rows = doc.select("tr");
        for(org.jsoup.nodes.Element row :rows)
        {
            org.jsoup.select.Elements columns = row.select("td");
            for (org.jsoup.nodes.Element column:columns)
            {
                System.out.print(column.text());
            }
            System.out.println();
        }

    }
}
