I am wondering if it is possible to publish Captivate files to epub. I see that there are now direct way of doing this, but as epub is packed HTML5, I wondered if it could be done by publishing HTML and convert it to epub. However the structure of the published HTML5 from Captivate is different from other unpacked epub files I have seen. Is it possible at all? Has anybody tried and succeeded or failed and can tell me if it is possible at all?
