[英]android:how to get tag from html
I'm trying to get specific tag from one web site. 我正在尝试从一个网站获取特定标签。 I can read the HTML but can't get the specific tag. 我可以阅读HTML,但无法获取特定标签。 Is there any way to do this task? 有什么办法可以完成这项任务? I was searching in other threads but I could not find the solution. 我在其他线程中搜索,但找不到解决方案。
Thanks in advance. 提前致谢。
Here is the code. 这是代码。
public class MainActivity extends Activity {
TextView text;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
text = (TextView)findViewById(R.id.text);
DownloadTask task = new DownloadTask();
task.execute("http://zodia.bg/sign/aries");
}
private class DownloadTask extends AsyncTask<String, Void, String>{
@Override
protected String doInBackground(String... urls) {
HttpResponse response = null;
HttpGet httpGet = null;
HttpClient mHttpClient = null;
String s = "";
try {
if(mHttpClient == null){
mHttpClient = new DefaultHttpClient();
}
httpGet = new HttpGet(urls[0]);
response = mHttpClient.execute(httpGet);
s = EntityUtils.toString(response.getEntity(), "UTF-8");
} catch (IOException e) {
e.printStackTrace();
}
return s;
}
@Override
protected void onPostExecute(String result){
text.setText(result);
}
}
} }
您可以对jsoup之类的东西使用DOM遍历,也可以手动使用String操作查找所需内容并解析出来( substring()
和indexOf()
等)。
