    }


    private String downloadUrl(String myurl) throws IOException {
        HttpURLConnection conn = null;
        try {
            URL url = new URL(myurl);
            conn = (HttpURLConnection) url.openConnection();
            BufferedInputStream buf = new BufferedInputStream(conn.getInputStream());
            BufferedReader bufreader = new BufferedReader(new InputStreamReader(buf, "utf-8"));
            String line = null;
            String page = "";
            while ((line = bufreader.readLine()) != null) {
                page += line;
            }
            return page;

        } finally {
            conn.disconnect();
        }
    }

이런식으로 구현했는데, 해결하고 싶은 문제가 뭐냐하면, EditText로 버스번호를 입력받아 

그 번호에 맞는 버스노선정보를 추출하고싶은데, 만약 77번을 검색하면 

778번 777번, 877번 등등 77이 포함된 모든 버스노선정보가 나오게됩니다. 

이부분을 어떻게 해결할 수 있을까요? 

//위치정보 코드는 잘랏습니다. 8000자에 걸린다고 하네요.

Answer 1

내부에서 사스파싱을 사용해서 모두 파싱하고 그오브젝트를 리스트로 만들어서 선택하게하시면 될듯합니다
