Parsing a Table/Div without Id alone from html to WebView Android

Issue

Im trying to parse a div or a table (pretty much the same for me because the table is within the div).

So I checked out that question: Load a div into a webview on Android

But the problem is that the div which Im working with doesnt have an Id. But it has a class.

So its like : <div class='CSSTableGenerator' style='width:820px'>

What can I do to show the div alone on the webview?

Code:

Document doc = null;
        try {
            doc = Jsoup.connect(url).get();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        Elements ele = doc.getElementsByClass("CSSTableGenerator");

        String html = ele.toString();
        String mime = "text/html";
        String encoding = "utf-8";
        webView.loadData(html, mime, encoding);

Solution

Use getElementsByClass()

Elements can have multiple classes (e.g. <div class="header round first">. This method checks each class, so you can find the above with el.getElementsByClass("header");.

In your case

Elements ele = doc.getElementsByClass("CSSTableGenerator");
