使用JSOUP從html表格提取非結構化數據

我一直在使用jSoup使用此代碼進行試驗。我們的想法是從這個頁面中提取的電影檔期：使用JSOUP從html表格提取非結構化數據

http://www.blitzmegaplex.com/en/schedule_movie.php?id=MOV1970

到目前爲止，我只能單獨提取電影的名稱。由於它使用特定的類名稱（「separator2」）進行標記。而其餘的則被命名爲「分隔符」。

我試圖建立使用循環以下步驟： 對於每一行表：

  1. 拿到電影院標題
  2. （步驟＃1行）跳過它下面一行。
  3. 獲得第二個名爲「分隔符」的類
  4. 從下面的所有行中獲取第二個（來自步驟＃3的行）。直到它到達包含名爲「separator2」的類的下一行
  5. 重複此過程，直到處理完所有行。

任何人都可以建議我該怎麼做？或者更好的建議？

謝謝。

我迄今爲止代碼：

public void getMovieSchedule(String movieUrl) throws IOException 
{ 


    //URL url = new URL(movieUrl); 
    //Document doc = Jsoup.parse(url, 3000); 

    //Element table = doc.select("table[div=scheduletbl]").first(); 
    //Iterator<Element> ite = table.select("tr").iterator(); 
    //ite.next(); // Skip the first row. 

    // Actual content 
    //print(ite.next().text()); 

    *** CODE ABOVE DOES NOT WORK *** 

    //final String urlSchedule = "http://www.blitzmegaplex.com/en/schedule_movie.php?id=MOV1970"; 

    Document doc = Jsoup.connect(movieUrl).get(); 
    Elements div = doc.select("div.panelbox"); 

    for(Element child : div) 
    { 
     Elements table = child.select("table"); 
     Elements row = table.select("tr"); // The actual content. 

     for (Element a: row) 
     { 
      Elements cinemaName = a.select("td.separator2"); 
      print(cinemaName.text().toString()); 
     } 
    } 
}

HTML被提取（一些代碼省略）：

如果我正確理解你的問題，你只需要提取一些細節從表（即電影名稱，日期和時間），但你有麻煩，因爲大多數行具有相同的className。

所以此基礎上，這裏是我的解決方案：

Elements e = doc.select("table#scheuletbl > tbody > tr > td"); 
for (Element el : e) { 
    if (el.hasClass("separator2")) System.out.println(el.text()); // cinema name 
    else if (el.toString().contains("colspan=\"2\"")) System.out.println(el.text()); // date 
    else if (el.hasAttr("rel")) System.out.println(el.text()); // times 
}

這將打印出：

BLITZMEGAPLEX - PARIS VAN JAVA, BANDUNG 
TUESDAY, 05 NOVEMBER 2013 
10:30    
13:15    
16:00    
18:45    
21:30    
BLITZMEGAPLEX - GRAND INDONESIA, JAKARTA 
TUESDAY, 05 NOVEMBER 2013 
10:45    
13:30    
16:15    
19:00    
21:45 

當然，該解決方案具有連接到該網站上的特定表，但由於只要格式不經常變化，並且在整個網站中保持一致，它就會起作用。您可以考慮創建一個類來存儲所有這些信息。
