Re: [docbook-apps] Generating multiple metadata elements in user.head.content

Thanks Bob, that's a nice solution. Inexplicably, calling the "person.name.last-first" template didn't apply the
    punctuation between surname and firstname (there was a space but no
    comma). I substituted in your custom template instead:

    

    <xsl:apply-templates select="d:personname/d:surname"/>

                  <xsl:text>, </xsl:text>

                  <xsl:apply-templates
    select="d:personname/d:firstname"/>

Hi Dave,

      
When processing an element that can appear
          zero or more times, I've found that creating a template that
          matches on that element and then using apply-templates works
          best. If there are no such elements, then the apply-templates
          does nothing.  If there are, it is applied as many times as
          there are elements.  Doing that in a
          new mode will prevent any interference from existing
          templates. 

      
 

      
This customization should do what you want.

      
 

      
 

      
<xsl:template name="user.head.content">

            <xsl:param name="node" select="."/>

            <xsl:param name="info" select="d:info[1]"/>

      
 

      
  <xsl:apply-templates 

              select="$info//d:authorgroup[@role='leadauthor']/d:author"

              mode="author.meta.mode"/>

          </xsl:template>

      
 

      
        

          <xsl:template match="d:author" mode="author.meta.mode">

                <meta name="dcterms:creator">

                    <xsl:attribute name="content">

                      <xsl:variable name="personname">

                        <xsl:choose>

                          <xsl:when test="d:personname/d:surname">

                            <xsl:call-template
          name="person.name.last-first"/>

                          </xsl:when>

                          <xsl:otherwise>

                            <xsl:call-template
          name="person.name"/>

                          </xsl:otherwise>

                        </xsl:choose>

                      </xsl:variable>

        

                     <xsl:value-of select="$personname"/>

        

        
          </xsl:attribute>  

                </meta>

          </xsl:template>

        
 

        
</xsl:stylesheet>

        

        
I called a couple of utility templates from
          common/common.xsl to arrange the author information in a
          temporary variable named 'personname', and then took the value
          of the result to eliminate html span wrappers and reduce it to
          plain text for the attribute value.

        I have two book author names marked up in
        <authorgroup>:

      
<authorgroup role="leadauthor">

                                             
          <author>

                                             
                      <personname><honorific>Mr</honorific><firstname>John</firstname><surname>Smith</surname></personname>

                                                         
          <contrib>Lead author
          contribution</contrib>

          <address>Org address</address>

                                                         
          </affiliation>

                                             
          </author>

                                             
          <author>

                                                         
          <personname>Name of second
          lead author</personname>

                                             
          </author>

                                  </authorgroup>

      
 

      
My first issue is trying to generate both
        <author> names in separate meta elements in HTML5 using
        1.78.1-ns. This is all I get:

      
<meta name="dcterms:creator" content="Smith, John" />

      
I have a customization that generates only
        the first author’s names (firstname and surname) – I don’t get
        the second author, nor do I get any content inside only
        <personname> (so far I need both <firstname> and
        <surname> to generate content):

      
<xsl:template name="user.head.content">

              <xsl:param name="node" select="."/>

              <xsl:variable name="info" select="(d:info)[1]"/>

      
…

      
<xsl:if test="$info and
          $info//d:author[ancestor::d:authorgroup[@role='leadauthor']]">      

                <meta name="dcterms:creator">

                    <xsl:attribute name="content">

                      <!--<xsl:call-template
          name="person.name.last-first">

                    <xsl:with-param
          name="node" select="."/>

                  </xsl:call-template>-->

                        

                      <xsl:choose>

                        <xsl:when test="descendant::d:surname">

                          <xsl:value-of select="normalize-space(string($info/d:authorgroup[@role='leadauthor']/d:author/d:personname/d:surname))"/>

                          <xsl:text>, </xsl:text>

                          <xsl:value-of select="normalize-space(string($info/d:authorgroup[@role='leadauthor']/d:author/d:personname/d:firstname))"/>

                        </xsl:when>

                        <xsl:otherwise>

                          <xsl:value-of select="normalize-space(string($info/d:authorgroup[@role='leadauthor']/d:author/d:personname))"/>    

                        </xsl:otherwise>

                      </xsl:choose>

                    </xsl:attribute>  

                </meta>

                

              </xsl:if>

      
…

      
</xsl:template>

      
 

      
I tried using xsl:for-each around the
        <meta> coding, and then again inside <meta>, but
        that generates the first author’s name multiple times in one
        <meta> element. I can’t see any clues from the EPUB
        metadata stylesheets either.

      
So: (1) How do I generate one meta element
        *for each author*, and (2) What coding works to generate content
        marked up in <personname> only (i.e. no child elements)?
