HTML Processor for XML XSL output

First apologies if this is not the right list to be posting to but after
searching over the XSL-List archives if this isn't the correct list I'm sure
someone can point me in the right direction.

I am searching for a solution to process HTML/XHTML into FOP compliant XML -
XSL documents.  The two solutions provided in the Resources section of the
FOP documentation, html2fo and wh2fo, seem to partially fulfill this
requirement but fail more often than not.  Also they seem rather inflexible
by not supporting any of the DTD types or CSS types.  For instance you
cannot parse the HTML specifying the DOCTYPE (e.g. 4.0.1 Transitional).

Does there exist a tool that can do this preferrably with a Java interface?

I seem to find every other type of parser but none for HTML -> XML-XSL

Thanks for any advice.

Steven
