I think what people ultimately want is the rich content of WordPress posts and Xenforo comments in both Wordpress and Xenforo.
Ultimately, this is why I chose to use XenPorta articles to replace WordPress entirely in lieu of any WordPress bridge since I can host the rich content as an article directly in Xenforo with Xenforo comments.
Note, since I've had to migrate content from WordPress in a semi-automated fashion, here is what I do:
- Use HTML Tidy to convert HTML from a rendered WordPress page (for the content div) to plain elements (no CSS or attributes)
- Replace angle brackets (html) with square brackets (bb code)
- Replace
h1
, h2
, h3
, h4
, h5
with appropriate size
bb code
- Replace
a
elements with url
bb code
- Strip unsupported html elements (e.g.
thead
, tbody
- I keep table
, tr
, th
which are supported by Editor and BB Code Manager add-on)
The result is is nearly identical content in Xenforo. Your add-on could do something similar.
