如何在Android中获取HTML文档的JSON部分

Question

我想解析Android Studio中的JSON脚本，我必须获取JSON脚本，这是HTML文档的一部分，而不是HTML部分。是HTML文档中的其他JSON脚本，但我必须专门使用此部分/脚本以下是我必须使用的HTML文档的示例... （HTML文档是我不拥有的网页的源代码）

                            ...........other HTML parts
</script><script type="application/ld+json">
    [                       ...........start of the JSON part
     {
      "@context":"http://schema.org",
       "@type":"Event",
            ...             ...........other JSON data
         "name": "EasyLearning Tre"
        }
       ] 
     }
    ]                       ...........end of the JSON part
  </script><div class="eh-carousel-header row">
                            ...........other HTML parts

我已经使用ASyncTask下载了整个HTML文档，现在我想获得本文档的JSON部分。这是我尝试过的......

public class MainActivity extends AppCompatActivity {
EditText urlContents;
String content=null;
Button navigate;
StringBuilder sb;

    public void navigate(View v){

         DownloadContents downloadContents = new DownloadContents();

         try{
             navigate.setText("Downloading...");content=downloadContents.execute("https://www.eventshigh.com/bangalore/technology?src=home").get();
         }catch(Exception e){
            e.printStackTrace();
            Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
        }
    }


    public class DownloadContents extends AsyncTask<String,Void ,String> {

        String result="";
        @Override
        protected String doInBackground(String... urls) {
            try {
                sb = new StringBuilder();
                URL url = new URL(urls[0]);

                HttpURLConnection connection = (HttpURLConnection)url.openConnection();
                connection.connect();

                InputStream in = new BufferedInputStream(connection.getInputStream());
                BufferedReader reader = new BufferedReader(new InputStreamReader(in,"iso-8859-1"),8);
                String line = null;

                while((line = reader.readLine())!=null){
                    sb.append(line + "\n");
                }
                result = sb.toString();
                in.close();


                return result;

            } catch (Exception e) {
                return e.toString();

            }
        }

       @Override
        protected void onPostExecute(String result) {
            super.onPostExecute(result);
            navigate.setText("Downloaded...");          

            String[] splitResult= result.split("</script><script type=\"application/ld+json\">");

            String[] nextSplitResult=splitResult[1].split("<script><div class=\"eh-carousel-header row\">");
            String mainResult=nextSplitResult[0];
            urlContents.setText(mainResult);


        }
    }
}

但我发现，拆分功能并没有拆分文件。

非常感谢任何帮助。
