Android jsoup选择表格单元格

Question

嗨，我试图从网站（http://omhc.nl/site/default.asp?Option=10017 & m = 1）获取一些信息。表结构是：

<tr> 
    <td colspan="4" style="border-bottom: 1px solid rgb(0, 0, 0);" width="100%">donderdag 19 april 2012&nbsp;</td> 
</tr> 
<tr> 
    <td width="5%">&nbsp;</td> 
    <td width="25%">17:00 - 22:00&nbsp;</td> 
    <td bgcolor="" width="40%">KM</td> 
    <td width="6%">Barhoofd&nbsp;</td> 
</tr> 
<tr> 
    <td colspan="4" style="border-bottom: 1px solid rgb(0, 0, 0);" width="100%">vrijdag 20 april 2012&nbsp;</td> 
</tr> 
<tr> 
    <td width="5%">&nbsp;</td> 
    <td width="25%">16:30 - 19:30&nbsp;</td> 
    <td bgcolor="" width="40%">Ouders/verzorgers van VL</td> 
    <td width="6%">Bardienst&nbsp;</td> 
</tr> 
<tr> 
    <td width="5%">&nbsp;</td> 
    <td width="25%">16:30 - 19:30&nbsp;</td> 
    <td bgcolor="" width="40%">Ouders/verzorgers van AvdN</td> 
    <td width="6%">Bardienst&nbsp;</td> 
</tr> 
<tr> 
    <td width="5%">&nbsp;</td> 
    <td width="25%">16:30 - 21:00&nbsp;</td> 
    <td bgcolor="" width="40%">EdK</td> 
    <td width="6%">Barhoofd&nbsp;</td> 
</tr> 
<tr> 
    <td width="5%">&nbsp;</td> 
    <td width="25%">21:00 - 23:00&nbsp;</td> 
    <td bgcolor="" width="40%">FK</td> 
    <td width="6%">Barhoofd&nbsp;</td> 
</tr> 
<tr> 
    <td width="5%">&nbsp;</td> 
    <td width="25%">23:00 - 00:00&nbsp;</td> 
    <td bgcolor="" width="40%">SW</td> 
    <td width="6%">Barhoofd&nbsp;</td> 
</tr> 

我的代码：

package maartenbrakkee.bardienst.omhc; 

import java.util.List; 

import org.jsoup.Jsoup; 
import org.jsoup.nodes.Element; 
import org.jsoup.nodes.Document; 
import org.jsoup.select.Elements; 

import android.app.Activity; 
import android.os.Bundle; 
import android.text.method.ScrollingMovementMethod; 
import android.widget.TextView; 

public class BardienstActivity extends Activity { 
    TextView tv; 
    static final String URL = "http://omhc.nl/site/default.asp?Option=10017&m=1"; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     tv = (TextView)findViewById(R.id.tv); 
     tv.setSingleLine(false); 

     try { 
      tv.setMovementMethod(new ScrollingMovementMethod()); 
      tv.setText(getBarschema()); 
     } catch (Exception ex) { 
      tv.setText("Error"); 
     } 
    } 

    protected String getBarschema() throws Exception { 
     String result = ""; 
     Document document = Jsoup.connect(URL).get(); 

     Elements dagen = document.select("tr:has(td[width=100%]) + tr:has(td[width=40%])"); 

     // Dag 
     String[] dag = new String[dagen.size()]; 
     int i = 0; 
     for (Element dagen1 : dagen) { 
      dag[i++] = dagen1.text() + "\n"; 
     } 

     return dag[3]; 
    } 
} 

我想获得天[0]：

donderdag 19 april 2012 + "\n" + 17:00 - 22:00 KM Barhoofd 

和天[1]：

vrijdag 20 april 2012 + "\n" + 16:30 - 19:30 Ouders/verzorgers van VL Bardienst "\n" + 16:30 - 19:30 Ouders/verzorgers van AvdN Bardienst + "\n" + 16:30 - 21:00 EdK Barhoofd + "\n" + 21:00 - 23:00 FK Barhoofd + "\n" 23:00 - 00:00 SW Barhoofd 

但我得到的只有17:00 - 22:00 KM Barhoofd [0]。如何选择正确的单元格（从第一个tr td [width：100％]直到下一个tr td [width：100％]）？

Answer 1

我改变一点点你的方法getBarSchema，主要的选择：

static protected List<String> getBarschema(String URL) throws Exception { 

    Document document = Jsoup.connect(URL).get(); 

    // New Selector 
    Elements dagen = document.select("div.content table tr td"); 

    // List better than array in this case 
    List<String> dag = new ArrayList(); 

    String line = ""; 
    for (Element dagen1 : dagen) {        

     String width = dagen1.attr("width");  
     if(width.equals("100%") && !line.equals("")){ 
      dag.add(line); 
      line =""; 
     }  
     line += dagen1.text() + "\n"; 
    }   
    return dag; 
}
