Hi Zeno,

here is a way to do one part in XSLT and another using a C program:

1. Use an XSLT stylesheet to convert MARC21 to MODS
   <http://www.loc.gov/standards/mods/v3/MARC21slim2MODS3.xsl>.

2. Then, use bibutils <http://sourceforge.net/projects/bibutils/>
   to convert MODS to your target formats. You will need:
   xml2bib   -   convert MODS into bibtex
   xml2ris   -   convert MODS into RIS format
 
Or if you can use Perl, do the conversion in one go using Catmandu
<https://librecatproject.wordpress.com/2014/12/11/day-9-processing-marc-with-catmandu/>.

Cheers,
Christian
