Question

我是Jsoup解析的新手。我能够进行凌空StringRequest来获取网站，但我在浏览复杂的标签并解析它时遇到了问题。

远程HTML

//Skipped the meta and header because I don't need it.
...
<body class="sin">
<div class="ks">
    <div class="wrap">

        <div class="content-right-sidebar-wrap">
            <main class="content">

                //A lot of unneeded tags

我正在使用此代码来获取并尝试解析它。

PostDetails

public class PostDetails extends AppCompatActivity{

    ...


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_post_details);

        ...
    }

    private void showDialog() {
        internetDialog = new AlertDialog.Builder(PostDetails.this)
        ...
    }

    private void loadPost() {
        Log.d(TAG, "loadPost called");

        final ProgressBar progressBar;
        progressBar = (ProgressBar) findViewById(R.id.progress_circle);
        progressBar.setVisibility(View.VISIBLE);


        String news_id = getIntent().getStringExtra("PostId");
        Log.d(TAG, "You clicked post id " + news_id);

        StringRequest stringRequest = new StringRequest(news_id,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        Log.d("Debug", response.toString());
                        if (progressBar != null) {
                            progressBar.setVisibility(View.GONE);
                        }
                        parseHtml(response);


                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        VolleyLog.d("", "Error: " + error.getMessage());

                        if (progressBar != null) {
                            progressBar.setVisibility(View.GONE);
                        }

                        final  AlertDialog.Builder sthWrongAlert = new AlertDialog.Builder(PostDetails.this);
                        ...
                        sthWrongAlert.show();
                    }
                });

        //Creating requestqueue
        RequestQueue requestQueue = Volley.newRequestQueue(this);

        //Adding request queue
        requestQueue.add(stringRequest);
    }





    private void parseHtml(String response) {
        Log.d(TAG, "parsinghtml");
        Document document = Jsoup.parse(response);

        //This is where I intend to parse the html
        //Element postTitle = document.select("");
    }


}

我需要解析<h1 class="post-title" itemprop="headline">和<div class="post-content" itemprop="text">中的文字。

请帮我解决一下这个问题？
