When doing .ToHtml() how to avoid the outer <p> element?

[thepra]

Can't quite figure out how to get rid of that <p> element in every parsed markdown.
My context is that I want to put the parsed markdown in the <summary> element, but <p> make the parsed text go to a new line, making an ugly looking summary.

Or even better it would nice to know how to choose with which outer HTML element parse the markdown to HTML.

Use String.Replace or a library like AngleSharp (for more advanced scenarios). There is no plan to customize in Markdig the HtmlRenderer for such scenarios.

You can also write a custom renderer based on the built-in ParagraphRenderer.

Something like

var pipeline = new MarkdownPipelineBuilder()
    .UseAdvancedExtensions()
    .Use(new MyParagraphExtension("summary"))
    .Build();

MyParagraphExtension.cs

public sealed class MyParagraphExtension : IMarkdownExtension
{
    private readonly CustomTagParagraphRenderer _renderer;

    public MyParagraphExtension(string tag)
    {
        _renderer = new CustomTagParagraphRenderer(tag);
    }

    public void Setup(MarkdownPipelineBuilder pipeline) { }

    public void Setup(MarkdownPipeline pipeline, IMarkdownRenderer renderer)
    {
        if (renderer is HtmlRenderer)
        {
            renderer.ObjectRenderers.ReplaceOrAdd<HtmlObjectRenderer<ParagraphBlock>>(_renderer);
        }
    }

    private sealed class CustomTagParagraphRenderer : HtmlObjectRenderer<ParagraphBlock>
    {
        private readonly string _openingTag;
        private readonly string _closingTag;

        public CustomTagParagraphRenderer(string tag)
        {
            _openingTag = $"<{tag}";
            _closingTag = $"</{tag}>";
        }

        protected override void Write(HtmlRenderer renderer, ParagraphBlock obj)
        {
            if (!renderer.ImplicitParagraph && renderer.EnableHtmlForBlock)
            {
                if (!renderer.IsFirstInContainer)
                {
                    renderer.EnsureLine();
                }

                renderer.Write(_openingTag);
                renderer.WriteAttributes(obj);
                renderer.Write('>');
            }
            renderer.WriteLeafInline(obj);
            if (!renderer.ImplicitParagraph)
            {
                if (renderer.EnableHtmlForBlock)
                {
                    renderer.WriteLine(_closingTag);
                }

                renderer.EnsureLine();
            }
        }
    }
}

This still puts in a

even for text without newlines. How do I turn that behavior off?

string.StartWith + replace and/or trim.
