C# Html parsing HtmlAgilityPack not working

Question

I am trying to read html table in order to read and change table with using HtmlAgilityPack. I tried with very different websites but my code does not work.

SelectSingleNode function returns null. Also when I call SelectNodes instead of SelectSingleNode, result is null again.

Example link http://www.uefa.com/livescores/ has a table. How can I read this table?

HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml("http://www.uefa.com/livescores/");
var result = doc.DocumentNode.SelectSingleNode("//table");

but my code does not work What does not work? What errors do you see? Describe what is happening. — Jasen

You're using the LoadHtml method which is used to load a HTML string, not load HTML from a URL. However, the Load method does not appear to support loading content from a URL and you may need to download the HTML separately and then load it it into the HtmlDocument class to use it.

For example:

var url = "http://www.uefa.com/livescores/";
var content = new System.Net.WebClient().DownloadString(url);

var doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(content);
var hn = doc.DocumentNode.SelectSingleNode("//table");

You can also use the HtmlWeb utility class:

var web = new HtmlWeb();
var doc = web.Load(url);
var hn = doc.DocumentNode.SelectSingleNode("//table");

If output of parsing is wrong, is there anything to fix? Because mine result is not true. All of the </td> </tr> are at end of result. I could not share my actual web page. But result like below <td><a href=test>test</a> <td alıgn="right">7 <tr><td><a href=test">test</a> <td><a href="a.html">test</a> <td alıgn="right">5 .... </td></td></tr></td></td></td></tr></td></td></td></tr></td></td></td>

If you have a valid HTML document, you can use any XPath statement to select the markup that you need.

There is a hr tag inside html, so xpath also gives error. When I remove hr tags manually it fixes. Because hr does not have any closing like </hr> Am i wrong?
