HTML Linq with HtmlAgilityPack, or alternative, in PCL

HtmlAgilityPack is a popular HTML parser library that allows you to parse and manipulate HTML documents using LINQ syntax. Here's an example code snippet that demonstrates how to use HtmlAgilityPack to extract all links from an HTML document:

using HtmlAgilityPack;

var html = "<html><body><a href='https://example.com'>Example</a></body></html>";
var doc = new HtmlDocument();
doc.LoadHtml(html);

var links = doc.DocumentNode.Descendants("a")
    .Select(a => a.Attributes["href"].Value)
    .ToList();

In this code, html is the HTML document that you want to parse. The HtmlDocument class is used to create a new HTML document object. The LoadHtml method is used to load the HTML document into the HtmlDocument object.

The LINQ expression extracts all links from the HTML document by selecting all descendant a elements and projecting their href attribute values to a list.

HtmlAgilityPack is available as a NuGet package and can be used in .NET projects that target the full .NET Framework or .NET Core.

If you need to use a HTML parsing library in a portable class library (PCL), you can use the AngleSharp library. AngleSharp is a modern, standards-compliant HTML parser that supports LINQ queries and is available as a PCL. Here's an example code snippet that demonstrates how to extract all links from an HTML document using AngleSharp:

using AngleSharp.Html.Parser;

var html = "<html><body><a href='https://example.com'>Example</a></body></html>";
var parser = new HtmlParser();
var doc = parser.ParseDocument(html);

var links = doc.QuerySelectorAll("a")
    .Select(a => a.GetAttribute("href"))
    .ToList();

In this code, html is the HTML document that you want to parse. The HtmlParser class is used to create a new HTML parser object. The ParseDocument method is used to parse the HTML document into a DOM tree.

The LINQ expression extracts all links from the HTML document by selecting all a elements using the QuerySelectorAll method and projecting their href attribute values to a list.

AngleSharp is available as a NuGet package and can be used in .NET projects that target the full .NET Framework, .NET Core, or .NET Standard.
