[OPEN-ILS-DEV] [OPEN-ILS-GENERAL] Cannot save authority record with a 155 field

[Linda Jansova]

Dear Josh,

Thank you for letting me know about the right XSL file!

After some more investigations I have come to a conclusion that it is 
not actually a 155 field which causes the problem but a 755 field. If it 
has any value in second indicator, xsltproc fails to process it. When 
the indicator does not have any value (or, to be more precise, there is 
just a space), it is okay.

So far, it seems that we will have to get rid either of the values of 
indicators in 755s, or of the following part of the XSL file:

<xsl:when
                 test="(700 <= ancestor-or-self::marc:datafield/@tag 
and ancestor-or-self::marc:datafield/@tag <= 755 ) and @ind2='7'">
                 <xsl:attribute name="authority">
                     <xsl:value-of select="marc:subfield[@code='2']"/>
                 </xsl:attribute>
             </xsl:when>

Hopefully it will work for us and let us proceed in the upgrade :-)!

Linda
