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.

Subject: [docbook-apps] Generating multiple metadata elements in
user.head.content
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>
<affiliation>
<shortaffil>Short
affil.</shortaffil>
<jobtitle>Job
title</jobtitle>
<orgname>Organisational affiliation</orgname>
<orgdiv>Org
div</orgdiv>
<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)?
