Class HtmlToMarkdownConverter

java.lang.Object

com.composum.ai.backend.base.service.chat.impl.HtmlToMarkdownConverter

public class HtmlToMarkdownConverter
extends Object

A quick HTML markdown converter that handles the tags [a, strong, code, em, p, br, u, ul, li, ol] used in rich text editor. Not threadsafe, use only once.

We do not want to use a library since the libraries doing this have many parts and are quite some work to deploy, and we only need to convert a few tags from richtext editors. Original generated by ChatGPT with "Please make an HTML to Markdown converter that handles the tags [a, strong, code, em, p, br, u, ul, li, ol] . Use the jsoup library for that." but some heavy rewrite.
