AgilityHtmlPack is a .NET library that provides a simple and flexible way to parse and manipulate HTML documents. It is an alternative to the more commonly known HTML parsing libraries like HtmlAgilityPack and AngleSharp. AgilityHtmlPack is designed to be lightweight, fast, and easy to use, making it an excellent choice for projects where performance and simplicity are paramount.

Lightweight and Fast: AgilityHtmlPack is built with performance in mind. It has a small memory footprint and is optimized for speed, making it ideal for processing large HTML documents efficiently.

CSS Selector Support: The library allows developers to use CSS selectors to target specific elements in the HTML document, simplifying the extraction process and reducing the amount of boilerplate code.

Fluent API: AgilityHtmlPack's fluent API provides a clean and intuitive syntax, making it easier for developers to navigate and manipulate the HTML document's elements and attributes.

HTML Modification: In addition to parsing HTML content, AgilityHtmlPack allows developers to modify the HTML document by adding, removing, or updating elements and attributes.

Now let's dive into the steps to parse HTML using AgilityHtmlPack in a .NET application:

First, create a new .NET project (Console Application, ASP.NET, etc.), and then install AgilityHtmlPack via NuGet Package Manager or the Package Manager Console:

In this example, we will load an HTML document from a URL and parse it using AgilityHtmlPack. Replace the your_html_url with the actual URL of the HTML document you want to parse.

            // Load the HTML document from a URL

            string htmlUrl = "your_html_url";

            WebClient client = new WebClient();

            string htmlContent = client.DownloadString(htmlUrl);

            var parser = new HtmlParser();

            var document = parser.ParseDocument(htmlContent);

            // Now, you can work with the HTML document

            // For example, let's extract the titles of all the anchor tags in the document

            var anchorTags = document.QuerySelectorAll("a");

            foreach (var anchor in anchorTags)

                Console.WriteLine(anchor.TextContent);

Step 3: Extract Data using CSS Selectors:

AgilityHtmlPack's CSS selector support simplifies data extraction from specific elements in the HTML document. In the example above, we used the QuerySelectorAll method to target all anchor tags (<a>) in the document and extracted their text content.

AgilityHtmlPack is a powerful and lightweight HTML parsing library for .NET applications. Its simplicity, speed, and CSS selector support make it an excellent choice for developers looking to extract data from HTML documents quickly and efficiently. In this blog, we learned about AgilityHtmlPack's key features and how to use it to parse HTML content and extract relevant information. Whether you are building web scraping applications, data extraction tools, or any project involving HTML parsing, AgilityHtmlPack can be a valuable addition to your .NET toolbox.
