通過Android/jsoup以URL格式抓取數據

Question

我試圖從HTML表中抓取URL，但是每次我都會得到HREF標題數據而不是URL - 是否有人可以解決/避免這種情況？

<table class="datagrid"> 
     <tr> 
      <th>Number</th> 
      <th>Name</th> 
      <th>Sex</th> 
      <th>Location</th> 
     </tr> 

      <tr> 
       <td><a href="redirector.cfm?ID=93bd5121-7a3b-4a56-a576-f432e542047a&page=1&&amp;lname=&amp;fname=" title="501207593">501207593&nbsp;</a></td> 
       <td>AARON, JUSTIN COLBY&nbsp;</td> 
       <td>M&nbsp;</td> 
       <td>Facility 1</td> 
      </tr> 

      <tr> 
       <td><a href="redirector.cfm?ID=c5629a92-7113-487c-ba9b-1e62203ab08d&page=1&&amp;lname=&amp;fname=" title="501302750">501302750&nbsp;</a></td> 
       <td>AARONSON, CARY HOWARD&nbsp;</td> 
       <td>M&nbsp;</td> 
       <td>Facility 2</td> 
      </tr> 

      <tr> 
       <td><a href="redirector.cfm?ID=66d01768-5686-44eb-ac6a-16eb783f52d0&page=1&&amp;lname=&amp;fname=" title="501306284">501306284&nbsp;</a></td> 
       <td>ABBOTT, LAUREA &nbsp;</td> 
       <td>F&nbsp;</td> 
       <td>Facility 3</td> 
      </tr> 

來源：

public class MainActivity extends Activity { 

    TextView tv; 
    String url = "http://google.com"; 
    String tr; 
    Document doc; 

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

     tv = (TextView) findViewById(R.id.TextView01); 
     new MyTask().execute(url); 
    } 

    private class MyTask extends AsyncTask<String, Void, String> { 

     ProgressDialog prog; 

     String title = ""; 

     @Override 
     protected void onPreExecute() { 
      prog = new ProgressDialog(MainActivity.this); 
      prog.setMessage("Loading...."); 
      prog.show(); 
     } 

     @Override 
     protected String doInBackground(String... params) { 
      try { 
       doc = Jsoup.connect(params[0]).get(); 
       Element tableElement = doc.select(".datagrid").first(); 

       Elements tableRows = tableElement.select("tr"); 
       for (Element row : tableRows) { 
        Elements cells = row.select("td"); 
        if (cells.size() > 0) { 
         title = cells.get(0).text() + "; " 
           + cells.get(1).text() + "; " 
           + cells.get(2).text() + "; " 
           + cells.get(3).text(); 
        } 
       } 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
      return title; 
     } 

     @Override 
     protected void onPostExecute(String title) { 
      super.onPostExecute(title); 
      prog.dismiss(); 
      tv.setText(title); 
     } 
    } 
} 

目前的結果：

501306284; ABBOTT，LAUREA; F ;設備3

期望的結果：

redirector.cfm ID = 66d01768-5686-44eb-ac6a-16eb783f52d0 &頁= 1 & & L-NAME = & FNAME = 「標題=」 501306284; ABBOTT，LAUREA; F ;基金3

或更好，但...

Answer 1

你似乎只是text越來越：

cells.get(0).text() 

我認爲這是你正在嘗試做

cells.get(0).child(0).attr("href")
