What's the easiest way to convert Wiki markup to HTML? [closed]

Question

I'm building a website that requires very basic markup capabilities. I can't use any 3rd party plugins, so I just need a simple way to convert markup to HTML. I might have a total of 3 tags that I'll allow.

What is the best way to convert ==Heading== to <h2>Heading</h2>, or --bold-- to <b>bold</b>? Can this be done simply with Regex, or does somebody have a simple function?

I'm writing this in C#, but examples from other languages would probably work.

Answer 1

Maybe this is what you need.

This page is a compilation of links, descriptions, and status reports of the various alternative MediaWiki parsers — that is, programs and projects, other than MediaWiki itself, which are able or intended to translate MediaWiki's text markup syntax into something else.

Answer 2

This really depends on the Wiki syntax you're using as there are several different ones. Obviously the wiki software has this functionality somewhere; if you can't find a software package that does this for you, you could start looking for the relevant code in your wiki software.

Answer 3

It's not really a simple problem, because if you're going to display things back to the user, you'll need to also sanitise the input to ensure you don't create any cross site scripting vulnerabilities.

That said, you could probably do something pretty simple as you describe most easily with a regular expression replacement.

For example

replace the pattern ==([^=]*)== with <h2>\1</h2>
