What is the best way to create a web page from FrameMaker?

I have recently started working at a company where we use FrameMaker to create our documentation and have been tasked with finding out how to turn the books that we write into web pages. I have tried saving the book files as HTML or XML files and converting the PDFs into HTML and XML. All of these has created a page that has poor formatting and doesn't reflect the original document very well. I have tried to edit the reference pages without any success, and editing via Notepad presented me with a wall of text and code that was unreadable.

Are there any options of better ways to create a web page from FrameMaker whilst keeping the formatting, or at least being able to edit it after without difficulty?

One option I have considered is using Dreamweaver, but as the company does not currently have a copy, I did not want to request it without knowing that it would be useful. Is it possible to take content directly from FrameMaker to Dreamweaver and then use that to format the content?

If you need any more information, please ask, any help would be more than welcome.
