Hi,
i dont know whether this would be helpful....May be u can do a
reverse engineering....
:-)
This is the transformation of FO to HTML.
The site is www.renderex.com
May be u can find something over there.......
Browsing XSL FO
XSL Formatting Objects are an XML dialect; why not render them to
HTML by an XSLT stylesheet? What you see below is the first
attempt to materialize this idea. It is created and maintained by
RenderX development team as an add-on to our principal product,
XEP.
Introduction
Here is the stylesheet: fo2html.xsl. Please download it and try to
view your favorite XSL FO documents in a browser. Don't expect the
result to be perfect - see below about limitations, but - look at
our demos! If you plan to extend it to cover more of the XSL spec,
please share your accomplishments with us.
Here are some examples produced by the stylesheet from FO files.
PDFs (generated by XEP) are also given; they serve as a reference
to assess the quality of their HTML counterparts. All examples
have been tested in IE5: for reasons explained below, we cannot
guarantee full interoperability with other browsers.

Possible Use
A stylesheet like this may be used to reduce the complexity in a
publishing system with multiple target media: you generate XSL FOs
from semantic XML data, and use it as a source for all other
presentation formats. When your data structure changes, you only
have to modify XML-to-XSLFO stylesheet.
Technical Notes
The stylesheet tries to convert XSL FO data into HTML+CSS1. CSS2
support is still rare among browsers, and hardly can be relyed
upon. Even with CSS1, there are many discrepancies between MS
Internet Explorer and Netscape Communicator. However, one can
hardly do this task without using any stylesheet capabilities at
all; so CSS1 seemed to be a common denominator.
It goes without saying that XSL FOs are much more powerful than
HTML+CSS1; moreover, since paged media are organized differently
from scrollable media, absolute similarity is not achievable.
Therefore, the conversion aims mostly at giving the user a
possibility to browse FO files, without pretending to preserve all
formatting subtleties predisposed for quality printing. The task
is also simplified by common vocabulary shared by XSL FO and CSS.
With this premises, the problem can be solved by amazingly simple
means: a 30 kb stylesheet does the bulk of the work.
Certainly, not everything can be achieved easily: for instance,
calculating the inheritance propagation along the FO tree is a
really tough task, as well as parsing CSS2 shorthands in XSLT. We
didn't even attempted to tackle this: in our opinion, this is more
easily achieved by a preprocessor. RenderX has such a preprocessor
built into XEP; redirecting its output into a file gives us a
"canonical" XSL FO document - with all shorthands expanded,
inheritance propagated, length units normalized etc.
However, if your XSL FO documents don't make use of shorthands,
multiple columns, absolutely positioned blocks and similar
advanced features, the results of the conversion can be very close
to the truth even without preprocessing, like in the examples
given above. This requires special care while writing XSL FO
stylesheets; but our experience shows it is relatively easy.

Thanks, I've been using the AntennaHouse version but it doesn't
translate tables in a way that satisifes FOP. Just thought
someone may have already solved this ?
