C# HTML Articles

File HTML

HTML is the most important document format in the world. The .NET Framework has the tools necessary for basic and advanced manipulation and creation of HTML, using regular expressions, StringBuilder, and strings. Here we see articles specific to HTML and its usage in the C# language.

HtmlTextWriter

There are many ways of handling HTML in the C# programming language. In this introductory program, we use the HtmlTextWriter type, which is an abstract data type for generating HTML markup. You can see that a span tag is opened and closed by the HtmlTextWriter.

Program that writes HTML [C#]

using System;
using System.IO;
using System.Web.UI;

class Program
{
    static void Main()
    {
	using (StringWriter stringWriter = new StringWriter())
	using (HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter))
	{
	    htmlWriter.RenderBeginTag(HtmlTextWriterTag.Span);
	    htmlWriter.Write("Perls");
	    htmlWriter.RenderEndTag();
	    Console.WriteLine(stringWriter);
	}
    }
}

Output

<span>Perls</span>

Manipulate

These articles demonstrate various aspects of how you can manipulate, generate, or remove HTML markup using the C# language. You can also encode entities in HTML.

Scrape

In programming, the term scraping means to download web pages and then scan the text and take parts into another application. You can use the C# language to scrape HTML links from web pages. This can be used to gather information from third-party sources. Please don't do anything illegal.

Colors

Many different named colors are available in the hypertext markup language. These can also be specified directly inside CSS files. In this article, I print out all the HTML colors using the C# language.

Validate

A lot of HTML is invalid. You can detect invalid HTML using the C# language; these two articles provide a simple and a more complex algorithm for doing this.

Summary

In the real world, parsing HTML is fairly difficult because we must support badly formed markup. On the other hand, XML is easy to parse because it has strict rules for correctness. If you need to store data, using XML is often better than HTML because it is easier to handle in code.
