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)?
