How Can I Parse CSS Files in C# Using HtmlAgilityPack?

Parsing CSS in C#

In C#, parsing CSS can be accomplished through using a CSS parser library. These libraries provide a convenient method to convert CSS into a structured data model that can be more easily manipulated and interrogated.

One popular option is HtmlAgilityPack. This open-source library allows you to parse HTML and CSS documents, providing an API for extracting specific elements and their attributes. To use HtmlAgilityPack to parse CSS, you can follow these steps:

1. Install the HtmlAgilityPack package using NuGet:

   Install-Package HtmlAgilityPack

2. Create an instance of the HtmlDocument class and load the CSS file into it:

   HtmlDocument doc = new HtmlDocument();
   doc.Load("style.css");

3. Use the DocumentNode property to retrieve the root node of the CSS document:

   HtmlNode rootNode = doc.DocumentNode;

4. Utilize the SelectSingleNode method to find specific CSS rules based on their selectors:

   HtmlNode ruleNode = rootNode.SelectSingleNode("body");

5. Extract the CSS properties and their values from the rule node:

   foreach (HtmlAttribute attr in ruleNode.Attributes)
   {
    Console.WriteLine($"{attr.Name}: {attr.Value}");
   }

By following these steps, you can effectively parse CSS files in C# using HtmlAgilityPack.
