Hi Magnus,

a slightly different approach I use when I need to filter on $2, below an example for 084. It has an advantage if you need to add separators between the fields as the for-each only has the nodes matching your criteria:

        <xsl:if test="marc:datafield[@tag=084]/marc:subfield[@code='2'][.='msc']">
            <span class="results_summary msc_classification">
                <span>MSC: </span>
                <xsl:for-each select="marc:datafield[@tag=084]/marc:subfield[@code='2'][.='msc']">
                    <a>
                        <xsl:attribute name="href"><xsl:value-of select="$SearchUrl"/>q=nlc,phr:<xsl:value-of select="str:encode-uri(../marc:subfield[@code='a'], true())"/><xsl:text> msc</xsl:text></xsl:attribute>
                        <xsl:value-of select="../marc:subfield[@code='a']" />
                    </a>
                    <xsl:choose><xsl:when test="position()=last()"><xsl:text></xsl:text></xsl:when><xsl:otherwise><span class="separator"> | </span></xsl:otherwise></xsl:choose>
                </xsl:for-each>
            </span>
        </xsl:if>

Hope that makes sense,

Katrin

try this :

<xsl:for-each select="marc:datafield[@tag='650']">
  <xsl:if test="marc:subfield[@code='x'] = 'x' or marc:subfield[@code='x'] = 'y'">
    <xsl:value-of test="marc:subfield[@code='a']">
  </xsl:if>
</xsl:for-each>

Kia ora!

I want to display most keywords as usual, but with an exception for those from the 650 field. Specifically, I want to display only those keywords that has the value "x" or "y" in subfield $2, and hide the other 650-keywords. Any hints on how to this in XSLT would be infinitely appreciated, and added to the wiki, so others can benefit from the solution.

Here is an example:

   <datafield tag="650" ind1=" " ind2="0">
     <subfield code="a">A</subfield>
     <subfield code="2">x</subfield>
   </datafield>
   <datafield tag="650" ind1=" " ind2="0">
     <subfield code="a">B</subfield>
     <subfield code="2">y</subfield>
   </datafield>
   <datafield tag="650" ind1=" " ind2="0">
     <subfield code="a">C</subfield>
     <subfield code="2">z</subfield>
   </datafield>
   <datafield tag="653" ind1=" " ind2="0">
     <subfield code="a">D</subfield>
   </datafield>

I want to display A and B (because they have $2 = x or y), and D (because it is not 650), but not C (because it is 650 and $2 is neither x nor y).

Best regards,
Magnus
