I don't think so. Since DSSSL is side-effect this is not possible.

You might consider writing a c++ program using the SP library and
have this program read the SGML file, insert the calculations and
write the result SGML file. The resulting SGML file can be parsed
by DSSSL since all the necessary calculations have been done.
