Generally all bookmark services and tools support HTML import
But it would be nice to have more export options: export from a group, export all bookmarks tagged..., export all bookmarks from date range... and this for all Diigo bookmarks, not just mine.
There are many tools out there, you could for example use:
http://www.ponyfish.com to filter out topics
then
http://www.rss2html.com to convert to HTML
