In today’s digital age, creating and manipulating HTML and SVG documents is essential for many software developers and businesses. Aspose.HTML for .NET is a powerful library that simplifies these tasks, offering various functionalities to work with HTML, SVG, and more. In this comprehensive guide, we’ll dive into the essentials of Aspose.HTML for .NET, breaking down each example into easy-to-follow steps. Whether you’re a seasoned developer or just getting started, you’ll find this guide invaluable for harnessing the capabilities of Aspose.HTML.

Prerequisites

Before we embark on this journey, let’s ensure you have everything you need:

• Development Environment: Make sure you have Visual Studio or any other .NET development environment installed on your computer.

• Aspose.HTML for .NET: You need to obtain the Aspose.HTML for .NET library. You can download it from here.

• Knowledge of C#: Familiarity with C# programming language is beneficial but not mandatory. This guide is designed to be beginner-friendly.

Import Namespace

To start using Aspose.HTML for .NET, you’ll need to import the necessary namespaces into your project. In your C# code, include the following namespace:

Step 1: Import Aspose.HTML Namespace

using Aspose.Html;

This namespace will grant you access to various HTML and SVG manipulation capabilities.

HTML to File

Step 1: Initialize an Empty HTML Document

// Initialize an empty HTML Document.
using (var document = new Aspose.Html.HTMLDocument())
{
    // Create a text element and add it to the document
    var text = document.CreateTextNode("Hello World!");
    document.Body.AppendChild(text);
    // Save the HTML to the file on disk.
    document.Save("document.html");
}

In this example, we create an HTML document and add a simple “Hello World!” text to it. We then save the HTML to a file on the disk.

HTML Without Linked File

Step 1: Prepare a Simple HTML File

System.IO.File.WriteAllText("document.html", "<p>Hello World!</p>" +
                                             "<a href='linked.html'>linked file</a>");

Here, we create a basic HTML file with an anchor link to another file.

Step 2: Load ‘document.html’ into Memory

using (var document = new Aspose.Html.HTMLDocument("document.html"))
{
    // Create Save Options instance
    var options = new Aspose.Html.Saving.HTMLSaveOptions();
    // Set the maximum handling depth to 0 to cut off linked HTML files.
    options.ResourceHandlingOptions.MaxHandlingDepth = 0;
    // Save the document
    document.Save(@".\html-to-file-example\document.html", options);
}

In this example, we load an HTML document into memory, set the maximum handling depth to cut off linked files, and save the document.

HTML to MHTML

Step 1: Prepare a Simple HTML File

System.IO.File.WriteAllText("document.html", "<p>Hello World!</p>" +
                                             "<a href='linked.html'>linked file</a>");

Just like in Example 2, we create a basic HTML file with an anchor link to another file.

Step 2: Load ‘document.html’ into Memory and Save as MHTML

using (var document = new Aspose.Html.HTMLDocument("document.html"))
{
    // Save the document as MHTML
    document.Save(@".\html-to-file-example\document.mht", Aspose.Html.Saving.HTMLSaveFormat.MHTML);
}

Here, we load the HTML document into memory and save it in MHTML format.

HTML to Markdown

Step 1: Prepare an HTML Code

var html_code = "<H2>Hello World!</H2>";

In this step, we define an HTML code snippet containing an <H2> element.

Step 2: Initialize Document from HTML Code and Save as Markdown

using (var document = new Aspose.Html.HTMLDocument(html_code, "."))
{
    // Save the document as a Markdown file.
    document.Save("document.md", Aspose.Html.Saving.HTMLSaveFormat.Markdown);
}

We create an HTML document from the code snippet and save it as a Markdown file.

SVG to File

Step 1: Prepare an SVG Code

var code = @"
    <svg xmlns='http://www.w3.org/2000/svg' height='80' width='300'>
        <g fill='none'>
            <path stroke='red' d='M5 20 l215 0' />
            <path stroke='black' d='M5 40 l215 0' />
            <path stroke='blue' d='M5 60 l215 0' />
        </g>
    </svg>";

Here, we create an SVG code that draws a simple, colorful graphic.

Step 2: Initialize an SVG Document from the Code and Save to Disk

using (var document = new Aspose.Html.Dom.Svg.SVGDocument(code, "."))
{
    // Save the SVG file to the disk
    document.Save("document.svg");
}

In this step, we create an SVG document from the code and save it as an SVG file.
