I don't know exactly what xhtml is,

but when you saying it's much more structured,

it may seem like CSS.

I'm importing/exporting html (with CSS) into RVF,

and it seems to work perfect.

I only have one litle problem with empty lines, but there's a workaround

for it.

You've to modify the htmlimporter as I described a few weeks ago.

If you're interested, I can send you the modified version.
