OAI-PMH XSLT library

You can use XSLT to alter the MARCXML output by Koha's OAI-PMH server. This paqe aims to collect some tips and tricks that might be useful.

See the documentation for advice on how you configure Koha to use custom XSLT for OAI-PMH output.

This transformation will remove the existing 001 field, and add a new 001 field that hs the biblionumber as its value.
