Sample Code

Here is a basic example of how to use Html Agility Pack in C# to load an HTML document and select nodes using XPath:

using System;
using HtmlAgilityPack;

class Program
{
    static void Main()
    {
        var web = new HtmlWeb();
        var doc = web.Load("http://example.com");

        // Select nodes using XPath
        var nodes = doc.DocumentNode.SelectNodes("//a[@href]");

        foreach (var node in nodes)
        {
            Console.WriteLine($"Text: {node.InnerText}, Href: {node.Attributes["href"].Value}");
        }
    }
}

In summary, while there is no official support line for Html Agility Pack, the community offers a wealth of resources including forums, Stack Overflow, GitHub, and various online articles and tutorials.
