Sometimes, you may want to customize the Markdown conversion rules to include or exclude specific HTML elements. In this example, we will define rules for converting only selected elements.

Step 1: Define Markdown Rules

First, create an HTML document as shown in the previous example. Then, create a MarkdownSaveOptions object to specify the conversion rules.

string dataDir = "Your Data Directory";
using (var document = new Aspose.Html.HTMLDocument("<p>my first paragraph</p>", dataDir))
{
    var options = new Aspose.Html.Saving.MarkdownSaveOptions();
    
    // Set the rules: only <a>, <img>, and <p> elements will be converted to markdown.
    options.Features = MarkdownFeatures.Link | MarkdownFeatures.Image | MarkdownFeatures.AutomaticParagraph;
    
    document.Save(dataDir + "Markdown.md", options);
}
