Can I somehow customise math processing?

[MihaZupan]

Instead of modifying the parser/renderer, the easiest way to do something like this is likely to post-process the syntax tree before you render it

MarkdownPipeline pipeline = new MarkdownPipelineBuilder()
    .UseMathematics()
    .Build();

string markdown = "$e=mc^2$";

MarkdownDocument document = Markdown.Parse(markdown, pipeline);

foreach (MathInline math in document.Descendants<MathInline>())
{
    math.Content = new StringSlice(math.Content.ToString().Replace("e", "42"));
}

string html = document.ToHtml(pipeline);
// <p><span class="math">\(42=mc^2\)</span></p>

@MihaZupan it works good but escaping string that I put in content. So instead

<span class="katex">

I have:

<span class="katex"&gt

Can I somehow write just this part unescaped?
