Java HTML Parser -- jsoup

/**
* Jsoup is a Java HTML Parser that can directly parse a URL address and HTML text content. It provides a set of very labor-saving APIs that can be used to retrieve and operate data through DOM, CSS, and operations similar to jquery.
The main functions of jsoup are as follows:
1. parse HTML from a URL, file, or string;
2. Use the Dom or CSS selector to find and retrieve data;
3. HTML elements, attributes, and text can be operated;
Jsoup is released based on the MIT protocol and can be safely used in commercial projects.

Next let's take a look at an instance to get the website http://www.menneske.no/arukone/5x5/eng? Number = position of the number in the Table in 499

public static void main(String[] args) throws IOException {        Document doc = Jsoup.connect("http://www.menneske.no/arukone/5x5/eng/?number=499").get();        Elements contents = doc.getElementsByClass("arukone");        Elements datas = contents.get(0).getElementsByTag("table");        for (Element data : datas)         {            Elements trs=data.getElementsByTag("tr");            for (int i = 0; i<trs.size(); i++)             {                Elements tds = trs.get(i).getElementsByTag("td");                for(int j = 0; j<tds.size(); j++){                    if(!"".equals(tds.get(j).text())){                        System.out.println(tds.get(j).text()+","+i+","+j);                    }                }            }        }    }
