從android的html內容中提取td和標題標籤？

-1

我有像這樣的字符串變量內容中的html內容。我想從此html內容字符串中提取標題標記。爲了得到這個內容我正在使用方法status（）根據下。使用httpclient。從android的html內容中提取td和標題標籤？

String content="<html> 
<head> 
<META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW"> 
<META HTTP-EQUIV="Refresh" CONTENT="300"> 
<title>Relay Control - Cabin + Conference Logger</title> 
</head> 
<tr> 
<td valign=top width="17%" height="100%"> 
<table width="100%" height="100%" align=center border=0 cellspacing=1 cellpadding=0> 
    <tr><td valign=top bgcolor="#F4F4F4"> 
    <table width="100%" cellpadding=1 cellspacing=5> 

    <tr><td align=center> 

    <table><tr><td><a href="http://www.digital-loggers.com/1P.html"><img src="logo.gif" width=195 height=65 border=0 alt="Digital Loggers, Inc."></a></td> 

    <td><b><font size=-1>Ethernet Power Controller</font></b></td></tr></table> 
    <hr> 
    </td></tr> 



<tr><td nowrap><b><a href="/index.htm">Relay Control</a></b></td></tr> 
<tr><td nowrap><b><a href="/admin.htm">Setup</a></b></td></tr> 
<tr><td nowrap><b><a href="/script.htm">Scripting</a></b></td></tr> 


<tr><td nowrap><b><a href="/rtc.htm">Date/Time</a></b></td></tr> 
<tr><td nowrap><b><a href="/serial.htm">Serial Ports</a></b></td></tr> 

<tr><td nowrap><b><a href="/ap.htm">AutoPing</a></b></td></tr> 
<tr><td nowrap><b><a href="/syslog.htm">System Log</a></b></td></tr> 
<tr><td nowrap><b><a href="/logout">Logout</a></b></td></tr> 
<tr><td nowrap><b><a href="/support.htm">Support</a></b></td></tr> 
<tr><td nowrap><b><a href="/help/">Help</a></b></td></tr> 




</body> 
</html> 
";

所以現在，我想從這個網站的內容提取標題標籤，我用這個方法，但我不能讓

public static String status() { 


     StringBuffer stringBuffer = new StringBuffer(""); 
     BufferedReader bufferedReader = null; 
     try { 
      HttpClient httpClient = new DefaultHttpClient(); 
      HttpGet httpGet = new HttpGet(); 

      URI uri = new URI("http://10.1.1.82/index.htm"); 
      httpGet.setURI(uri); 
      httpGet.addHeader(BasicScheme.authenticate(
        new UsernamePasswordCredentials("admin", "kirti123"), 
        HTTP.UTF_8, false)); 

      HttpResponse httpResponse = httpClient.execute(httpGet); 

      HttpEntity entity = httpResponse.getEntity(); 
      Log.e("entity: ", "> " + entity); 

      // Read the contents of an entity and return it as a String. 
      content = EntityUtils.toString(entity); 

      Log.e("content: ", "> " + content); 


      // String result = httpResponse.toString(); 
      htmlDocument = Jsoup.connect(content).get(); 
      htmlContentInStringFormat = htmlDocument.title(); 
      Log.e("title: ", "> " + htmlContentInStringFormat); 

      InputStream inputStream = httpResponse.getEntity().getContent(); 
      bufferedReader = new BufferedReader(new InputStreamReader(
        inputStream)); 

      String readLine = bufferedReader.readLine(); 
      while (readLine != null) { 
       stringBuffer.append(readLine); 
       stringBuffer.append("\n"); 
       readLine = bufferedReader.readLine(); 
      } 
     } catch (Exception e) { 
      // TODO: handle exception 
     } finally { 
      if (bufferedReader != null) { 
       try { 
        bufferedReader.close(); 
       } catch (IOException e) { 
        // TODO: handle exception 
       } 
      } 
     } 
     return stringBuffer.toString(); 

    }

所以plz幫助我怎樣可以提取標題標籤？

試試這個：https://stackoverflow.com/questions/2188049/parse-html-in-android –

public String[] GetTags(String html, String tagName) { 

    List<String> result = new ArrayList<String>(); 

    String tagStart = "<" + tagName + ">"; 
    String tagEnd = "</" + tagName + ">"; 
    String tag_data; 
    int end_index = 0; 
    int last_index = 0; 
    int start_index = 0; 
    do { 

     start_index = html.indexOf(tagStart,last_index+1); 
     end_index = html.indexOf(tagEnd,last_index+1); 
     last_index = end_index; 
     if(end_index > 0) { 
      tag_data = html.substring(start_index + tagStart.length(),end_index); 
      result.add(tag_data); 
     } 
     else { 
      break; 
     } 

    }while(true); 

    return (String[]) result.toArray(); 
}

試試這個
