从WebSite获取HTML代码并删除不必要的代码-仅在WebView中显示表格

Question

I am trying to get my app to sync itself with a website, and display only the table of a website. 我正在尝试让我的应用与网站同步，并仅显示网站表格。 Example: Normal HTML framework, and the table is inside a div#table, so I did it pretty simple and built the HTML Framework: 示例：普通的HTML框架，并且该表位于div＃table内，因此我做起来非常简单，并构建了HTML框架：

String html = "<html> " +
        "<head>" +
        "</head>" +
        "<body style=\"background-color: transparent\">" +
        "?body" +
        "</body>" +
        "</html>";

And then I tried to replace the ?body with the table, but here's my problem: I have no clue how to do that and then load it into a transparent WebView. 然后，我尝试用表替换？body，但这是我的问题：我不知道如何执行此操作，然后将其加载到透明的WebView中。 I found a little bit code online, and tried to get it working for my case, so here's that: 我在网上找到了一些代码，并尝试使其适用于我的情况，所以这就是：

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    List<String> links = new ArrayList();
    setContentView(SliderCreator.createSlider(R.layout.activity_news, this));
    wv = (WebView) findViewById(R.id.newsWebView);
    wv.setBackgroundColor(Color.TRANSPARENT);
    try {
        String finalHTML = getIntent().getStringExtra("html");
        if (!finalHTML.contains("<html>")) {
            String css = "";
            for(String link : links) {
                css+=Utils.getHTML(link);
            }
            finalHTML = html.replace("?body", getIntent().getStringExtra("html")).replace("?css", css);
        }
        wv.getSettings().setJavaScriptEnabled(true);
        //open URLs in external Browser
        wv.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
                return true;
            }
        });
        wv.loadDataWithBaseURL("", finalHTML, "text/html", "UTF-8", "");
    } catch(Exception e) {
        Toast.makeText(this, "An error occured...", Toast.LENGTH_LONG).show();
    }

But that doesn't work.. Can somebody help me out get that working for me? 但这是行不通的。有人可以帮我解决这个问题吗？ (Btw.: I tried it with RegEx, didn't work, I tried it with JSoup, didn't work either...) （顺便说一句：我用RegEx尝试过，没用，我用JSoup尝试过，也没用...）

Answer 1

try using HTML Agility Pack if not working with RegEx 如果不适用于RegEx，请尝试使用HTML Agility Pack

Please note , your RegEx might not work the desired way if the text contains nested table tags 请注意 ，如果文本包含嵌套表标签，则RegEx可能无法正常工作
