Quoting Lou-at-home lou.burnard@computing-services.oxford.ac.uk:
You can't run XSLT on SGML files, so this is not a very sensible question as phrased. However, migrating SGML to XML is very easily done using a nifty utility called osx, of which we have just done a windows port (sorry, but the Mac version is still a glint in someone else's eye).
You may not be talking about the same thing, but I've been very happily converting SGML to XML using osx on my Powerbook for months. I installed it from the opensp3 package using fink (google fink for details). Wouldn't work on OS9, of course...
I'm not really familiar with everything that goes on in the background with SGML catalogs and so forth, but it certainly can work on a mac.
