Hmm, FORTRAN, Optimisation, XML, ... You don't work for NAG do you?:-)

I don't know of any Fortran specific XML tools. As one of the
demonstrators of the recent ESPRIT Openmath project
(http://www.nag.co.uk/projects/openmath)  we made a demonstrator taking
polynomials and constraints displayed on a web form (using an applet
derived from the publicly available webeq applet, displaying mathml)
to a minimisation routine in the NAG Fortran library. The communication
with the server running the numeric library was all in XML (using
OpenMath rather than MathML, but it's the same thing from some
viewpoint). The XML parsing code wasn't done in Fortran though: we used
higher level languages that took that data and passed it in a more
fortran friendly way to the optimisation routine, and converted the
results back to XML for passing back to the client in the web
form. Unfortunately the code for this is not available as it used
several proprietary products, however the general principle certainly works.

I'm not sure what you are asking about here, how to extend your DTD so
as to allow MathML (this is normally easy) or how to extend your tools
to understand MathML (this may or may not be hard depending on what your
tools do) or how to display MathML in your browser (Unless you are using
mozilla, this requires some plugin or applet or other such extension, at
the present time at least).
