Getting TextContent from OuterHtml in C# Using AngleSharp

When working with HTML content in your C# applications, you might encounter the challenge of extracting cleanly formatted text. A common issue arises when you want to retrieve text but the existing methods sometimes return text without any spaces, making it hard to read. In this guide, we will explore how to replace <br> tags with new lines to ensure that the text content is clean and readable, and we will go over how to use AngleSharp to achieve this.

The Problem

You may have found yourself in a situation where the TextContent method is returning text without appropriate spacing, particularly in a console application. For instance, if your HTML content includes line breaks, they may not be reflected in the text you retrieve. You might wonder if there's a way to replace every <br> tag with a new line and then extract the modified TextContent from that OuterHtml.

Let’s dive into a reliable solution that addresses this issue effectively.

The Solution

To achieve this clean extraction of text content with proper line breaks, we will use the AngleSharp library in C# . This library allows for easy manipulation of HTML documents. Below are the steps you would typically follow to get rich formatted text from your OuterHtml.

Step 1: Set Up AngleSharp

First, ensure that you have the AngleSharp library installed in your C# project. You can do this via NuGet Package Manager:

Step 4: Retrieve the Text Content

After making the replacements, you can simply retrieve the TextContent from the Body of the document. This content will now include the new lines where the <br> tags were previously located:
