I use FrameMaker mostly on a Mac. I need to do some heavy transformations on the documents (convert them to unstructured Frame to SGML). I wrote a bunch of scripts that parse and process MIF files (MIF is the Maker Interchange Format, a text format with angle brackets (but not SGML)).It is not really easy, MIF can be quite a pain to deal with, but it works quite well.

You should be able to do the same.

You can also use the FDK, the Frame Developer's Kit, which gives you a C API to Frame's internals. I have seen a module that could be a Perl wrapper for the FDK in a Perl module list (search for "Framemaker") but it seems to have disappeared from CPAN, you might want to get in touch with the author.
