https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=18369 --- Comment #8 from Paul Poulain <paul.poulain@biblibre.com> --- Katrin, it's not changing the default mapping, it's just removing a hardcoding of biblionumber in 001 in XSLT Instead of building the biblionumber from hardcoded 001 field, this patch send $biblionumber to the XSL, and uses it where needed : Send the biblionumber as parameter: + my $kohavars = "<koha>\n<biblionumber>$biblionumber</biblionumber>\n</koha>\n"; Instead of 001, us the $biblionumber: - <xsl:variable name="biblionumber" select="marc:controlfield[@tag=001]"/> + <xsl:variable name="biblionumber" select="marc:koha/marc:biblionumber"/> PS: not sure the patch is perfect, complete or valid. But I 100% agree with the fact that we must not assume that biblionumber is in 001. -- You are receiving this mail because: You are watching all bug changes.
