[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] functions and sequences
 I have this function (within a large stylesheet). It works if I comment out the two lines indicated with the comments, but I get a "E net.sf.saxon.xpath.DynamicError: A sequence of more than one item is not allowed as the result of function bib:reftype()" error otherwise. Is there some way to get this to work? I'm not really sure how much of the related code I need to show to have this make any sense! <xsl:function name="bib:reftype" as="xs:string"> <xsl:param name="bibref" as="element(mods:mods)?"/> <xsl:choose> <xsl:when test="$bibref/mods:relatedItem/@type = 'host'"> <xsl:variable name="issuance" select="$bibref/mods:relatedItem/mods:originInfo/mods:issuance"/> <xsl:choose> <xsl:when test="bib:refclass($bibref) = 'part-inSerial'"> <xsl:text>article</xsl:text> <!-- this code introduces a sequence error; don't know why --> <xsl:text>-</xsl:text> <xsl:value-of select="$bibref/mods:relatedItem/mods:genre"/> </xsl:when> <xsl:when test="bib:refclass($bibref) = 'part-inMonograph'"> <xsl:choose> <xsl:when test="$bibref/mods:genre"> <xsl:value-of select="$bibref/mods:genre"/> </xsl:when> <xsl:otherwise> <xsl:text>chapter</xsl:text> </xsl:otherwise> </xsl:choose> </xsl:when> <xsl:otherwise> <xsl:value-of select="$bibref/mods:genre"/> </xsl:otherwise> </xsl:choose> </xsl:when> <xsl:otherwise>book</xsl:otherwise> </xsl:choose> </xsl:function>
