Suggestion for improving reliablility and exensibility

[stephenafamo]

I've been thinking that perhaps we can use goldmark's AST as a middleground for converting HTML to MD.

• Parse HTML using net/html
• Walk through the tree and convert it into a goldmark ast node
• Use https://github.com/Kunde21/markdownfmt to convert from GoldmarkAST to markdown text.

I've been working on converting a different format into markdown, this method has been quite smooth as far as I can parse to AST correctly.

I was thinking that we could do a similar thing for HTML. Bonus point is that it'll make it easier to extend and support many markdown flavours and extensions. GFM is already covered.

This will likely be a breaking change since something like setting custom options will no longer work the same way.

If you think it makes sense I could work on it once I have less work on my hands.

Thanks your suggestion. I'm not good for the "different format". What the use-case?

I just think that first converting into an intermediate format makes things cleaner and more reliable, it'll also eliminate a number of weird edge cases.

I have some experience working with goldmark so I know it is quite nicely designed and works pretty well.

I got the idea because I was converting from prosemirror to markdown and back and it works quite seamlessly. I think doing the same for HTML may provide cleaner results.
