解析html頁面

Question

我想解析1個url和後綴，我想從中訪問一些數據。 html頁面的

try { 
     Document doc = Jsoup.connect("http://abc.com/en/currency/default.aspx").get();//abc is for example as i cant put site name 
     Elements td = doc.select("ctl00_ContentPlaceHolder1_currencylist_rptCurrencyList_ctl01_trList"); //this is the name of table row in html page i will show html page snippet also 
     String temp=td.val(); 
     info.setText(temp); 
    } 
    catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 

片段，我想分析如下：

 <tr id="ctl00_ContentPlaceHolder1_currencylist_rptCurrencyList_ctl01_trList"> 
<td width="400px" class="CurrencyListItems">    
     UK POUND 
     </td> 
<td width="60px;" class="CurrencyListItemsIN" align="center"> 
     5.72 
     </td> 
<td width="150px;" class="CurrencyListItemsLast"> 
      <table cellspacing ="0" cellpadding ="0" width="100%"> 
        <tr> 
        <td class="CurrencyListBANKNOTES" align="center">       
        5.625 
        </td> 
        <td class="CurrencyListBANKNOTES2" width="75px" align="center"> 

        5.75 
        </td> 
        </tr> 
      </table> 
     </td> 

我從上面的html英鎊想，5.625,5.75 我想上面的代碼，但THNG是不解析URL只是其強行出來，如果嘗試

Answer 1

試試這個：

Element tr = doc.getElementById("ctl00_ContentPlaceHolder1_currencylist_rptCurrencyList_ctl01_trList"); 

嘗試

String contents = tr.text().trim(); 
contents = contents.replaceAll("\\s+"," "); 
contents = contents. replaceAll("\\<.*?>","-"); 
String []values = contents.split("-"); 

或

Elements elements = tr.select("*"); 
for (Element element : elements) { 
    System.out.println(element.ownText()); 
}
