I'm still stuck on two unresolved problems. The first is this
grouping-related one. My problem is I end up with empty ul content
(that is invalid). Here was my message from last week ...
One problem with the below is that I can't work out how to only add the
nested ul element if there's content. I end up with this, for example:
<div class="slide">
<h2>Heading</h2>
<ul>
<li>Bullet 1a
<ul>
<li>B2
<ul></ul>
</li>
</ul>
</li>
<li>Bullet 1b
<ul>
<li>Bullet 2a
<ul></ul>
</li>
<li>Bullet 2b
<ul></ul>
</li>
</ul>
</li>
</ul>
</div>
Source fragment:
<bullets>
<bullet level="0" marker-type="inherited">
<content>Heading</content>
</bullet>
<bullet level="1" marker-type="inherited">
<content>Bullet 1a</content>
</bullet>
<bullet level="1" marker-type="inherited">
<content>Bullet 1b</content>
</bullet>
<bullet level="2" marker-type="inherited">
<content>Bullet 2a - “a
quote’’</content>
</bullet>
<bullet level="2" marker-type="inherited"
id="bullet-1">
<content>Bullet 2b</content>
</bullet>
</bullets>
templates:
<xsl:template match="key:bullets">
<xsl:choose>
<xsl:when test="../@master-slide-id='master-slide-1'">
<xsl:apply-templates select="key:bullet[(_at_)level='0']"
mode="title"/>
</xsl:when>
<xsl:otherwise>
<h2><xsl:value-of select="key:bullet[(_at_)level='0']"/></h2>
<ul>
<xsl:call-template name="process-level">
<xsl:with-param name="bullet" select="key:bullet"/>
<xsl:with-param name="level" select="1"/>
</xsl:call-template>
</ul>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template name="process-level">
<xsl:param name="bullet" required="yes" as="element()*"/>
<xsl:param name="level" required="yes" as="xs:integer"/>
<xsl:for-each-group select="$bullet[not(@level='0')]"
group-starting-with="*[xs:integer(@level) eq $level]">
<li><xsl:value-of select="normalize-space(.)"/>
<ul>
<xsl:call-template name="process-level">
<xsl:with-param name="bullet" select="current-group()
except ."/>
<xsl:with-param name="level" select="$level + 1"/>
</xsl:call-template>
</ul>
</li>
</xsl:for-each-group>
</xsl:template>
