[Koha-devel] XSLT to display keywords with 650$2 = x

[Andreas Roussos]

Hi Magnus,

Give the following a try:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
   xmlns:marc="http://www.loc.gov/MARC21/slim"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="UTF-8" indent="no"/>
<xsl:template match="marc:record">
   <xsl:if test="marc:datafield[starts-with(@tag,'65')]">
     <xsl:for-each select="marc:datafield[starts-with(@tag,'65')]">
       <xsl:if test="@tag=650">
         <xsl:for-each select="marc:subfield">
           <xsl:choose>
             <xsl:when test="@code='2'">
               <xsl:variable name="twoval" select="."/>
               <xsl:if test="($twoval='x') or ($twoval='y')">
                 <xsl:value-of select="preceding-sibling::*[@code='a']"/>
                 <xsl:text>&#xa;</xsl:text>
               </xsl:if>
             </xsl:when>
           </xsl:choose>
         </xsl:for-each>
       </xsl:if>
       <xsl:if test="@tag!=650">
         <xsl:for-each select="marc:subfield">
           <xsl:choose>
             <xsl:when test="@code='a'">
               <xsl:value-of select="."/>
               <xsl:text>&#xa;</xsl:text>
             </xsl:when>
           </xsl:choose>
         </xsl:for-each>
       </xsl:if>
     </xsl:for-each>
   </xsl:if>
</xsl:template>
</xsl:stylesheet>

Regards,
Andreas

P.S.: There's probably a much better way of doing this... ;-)
