android - 解析html页面

Question

我想解析 1 个 url 和后记，我想从中访问一些数据。

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();
    } 

我要解析的html页面 fragment 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>

我想从上面的 html 英镑，5.625,5.75 我试过上面的代码，但问题是它不是解析 URL，只是如果尝试它就出来了

Answer 1

试试这个:

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

尝试

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());
}
