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>
<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>
<xsl:template match="key:bullets"> <xsl:choose> <xsl:when test="../@master-slide-id='master-slide-1'"> <xsl:apply-templates select="key:bullet[@level='0']" mode="title"/> </xsl:when> <xsl:otherwise> <h2><xsl:value-of select="key:bullet[@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>
