Question

首先，我是德国人，不要因为我的英语不好而讨厌我;）

我正在上学的应用程序上工作。我的问题是，我需要的信息是在page的HTML文件中。有没有办法保存所有＆＃34; td＆＃34;数组或字符串中的标签？

HTML代码：

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">

这里是AsyncTask，当我点击按钮时执行：

    private class substitute extends AsyncTask<Void, Void, Void> {
    String monday;

    @Override
    protected Void doInBackground(Void... voids) {
        Document doc = null;
        try {
            doc = Jsoup.connect("http://www.dbg-filderstadt.de/fileadmin/dateien/Dokumente/w00000.htm").get();
        } catch (IOException e) {
            e.printStackTrace();
        }
        Elements myElements = doc.getElementsByClass("subst")
                         .first().getElementsByTag("td");

        for(Element element : myElements){
            monday = element.ownText();

        }

            return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        TextView tw1=(TextView)findViewById(R.id.textView1);
        tw1.setText(monday);
    }
}

关键是，这段代码只是给了我第一个表格的文本＆＃34; subst＆＃34;。我怎样才能从其他表中获取元素？

Answer 1

将星期一作为数组

  String[] monday

代替这个

   Elements myElements = doc.getElementsByClass("subst")
                     .first().getElementsByTag("td");

写下以下

   Elements myElements = doc.getElementsByTag("td");
   monday = new String[myElements.size()];

你将获得html页面中的所有td标签和
