[Koha] OPAC XSLT template: how to add text if the MARC field is not blank?

[King, Fred]

Hi everyone,

I'm editing the OPAC detail xslt file to display some extra fields. What I have now is this:

                                <xsl:if test="marc:datafield[@tag=698]">
           <span class="results_summary conference">
               <xsl:if test="marc:datafield[@tag=698]/@ind1=' '">
                   <span class="label">Conference: </span>
               </xsl:if>
               <xsl:for-each select="marc:datafield[@tag=698]">
                  <a><xsl:attribute name="href">/cgi-bin/koha/opac-search.pl?q=conference-name:"<xsl:value-of select="marc:subfield[@code='a']"/>"</xsl:attribute><xsl:value-of select="marc:subfield[@code='a']"/></a>
                    <a><xsl:attribute name="href">/cgi-bin/koha/opac-search.pl?q=conference-name:"<xsl:value-of select="marc:subfield[@code='c']"/>"</xsl:attribute><xsl:value-of select="marc:subfield[@code='c']"/></a>
                  <a><xsl:attribute name="href">/cgi-bin/koha/opac-search.pl?q=conference-name:"<xsl:value-of select="marc:subfield[@code='d']"/>"</xsl:attribute><xsl:value-of select="marc:subfield[@code='d']"/></a>
                  <a><xsl:attribute name="href">/cgi-bin/koha/opac-search.pl?q=conference-name:"<xsl:value-of select="marc:subfield[@code='e']"/>"</xsl:attribute><xsl:value-of select="marc:subfield[@code='e']"/></a>
               <xsl:if test="position()!=last()"><span class="separator"><xsl:text> | </xsl:text></span></xsl:if>
               </xsl:for-each>
           </span>
       </xsl:if>

Right now it appears on the details page as fieldafieldcfielddfielde. I'd like to add a comma between the fields.

I tried adding <xsl:text>, </xsl:text>, but if there are fields a and e but no c and d, for example, the OPAC display comes out as fielda, , , fielde.

Is there xsl for "if there's something in field c, then add a comma and a space, otherwise don't put anything there" so I can have fielda, fielde? It seems as if there ought to be one, but I haven't found it yet.
