Subject: RE: [xsl] Can't identify last ancestor node
This is close to what I need, but I need to be more
clear. In this case, the context node is
/menudata/menu/menu. I want to apply unique output for
the last <menu> nodes in /menudata/menu/menu. For
instance:
<menudata>
<menu name="link1">
<menu name="link1a"/>
<menu name="link1b"/>
<menu name="link1c"/>
</menu>
<menu name="link2">
<menu name="link2a"/>
<menu name="link2b"/>
<menu name="link2c"/>
</menu>
</menudata>
The <menu> nodes with name="link1c" and name="link2c"
are the nodes that I'm after, but I can't figure out
how to identify those nodes with XPath.
Working with <xsl:variable name="last-menu"
select="(//menu)[last()]"/> gives me the last <menu>
node in the entire nodeset, so that my custom output
is applied only to name="link2c". So maybe [last()] is
not the predicate that I need.
Thanks for bearing with me,

You haven't told us what the context node is for
your code snippets -
presumably it's the <menu> element that you're
testing? In that case they
don't make any sense at all. Looking at the
ancestors of a node can't tell
you whether it has any following siblings, for
example. (From your question,
I think you may have confused your ancestors with
your descendants).
Best way to do this is probably to set a global
variable to the last menu
element:
<xsl:variable name="last-menu"
select="(//menu)[last()]"/>
and then when processing each menu element, test
<xsl:if test=". is $last-menu"> (XSLT 2.0)
<xsl:if test="generate-id(.) =
generate-id($last-menu)"/> (XSLT 1.0)

Subject: [xsl] Can't identify last ancestor node
Using this XML data:
<menudata>
<menu name="link1"/>
<menu name="link2">
<menu name="link2a"/>
<menu name="link2b"/>
</menu>
</menudata>
I am producing this HTML output:
<ul>
<li>link1</li>
<li>link2
<ul>
<li>link2a</li>
<li>link2b</li>
</ul>
</li>
</ul>
I am using a convoluted stylesheet that tokenizes
an
attribute and generates the HTML output based on
the
attribute's value. My problem is identifying the
last
nested node, in this example "link2b", so that I
can
customize that node's output.
My complete stylesheet is below, but to summarize
I
made two attempts:
<xsl:for-each select="ancestor::menu">
<xsl:if test="position()=last()">
<xsl:text>Write custom end text here</xsl:text>
</xsl:if>
</xsl:for-each>
and
<xsl:if test="ancestor::menu[last()]">
<xsl:text>Write custom end tag here</xsl:text>
</xsl:if>
Both attempts wrote to each individual node, not
just
the last one. How can I tell my stylesheet to
write
one thing for the last <menu> node, and something
else
for the rest?
Here's the entire stylesheet:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="html" indent="yes"/>
<!-- siteID determines if a link is displayed for
a
specific cobrand -->
<xsl:param name="siteID" select="2"/>
<!-- Displays navigation -->
<xsl:template match="/">
<ul>
<!-- tokenize all <menu> nodes -->
<xsl:for-each select="//menu">
<!-- Tokenize attributes to check if siteID is
excluded -->
<xsl:call-template name="tokenize">
<xsl:with-param name="string"
select="@exsites"/>
<xsl:with-param name="delimiters"
select="','"/>
<xsl:with-param name="level"
select="'process-includeExclude'"/>
</xsl:call-template>
</xsl:for-each>
</ul>
</xsl:template>
<!-- Extract individual values from
comma-delimited
attribute -->
<xsl:template name="tokenize">
<xsl:param name="string" select="''" />
<xsl:param name="delimiters" select="'
'"
/>
<xsl:param name="level" select="''" />
<xsl:call-template name="_tokenize-delimiters">
<xsl:with-param name="string" select="$string"
/>
<xsl:with-param name="delimiters"
select="$delimiters" />
<xsl:with-param name="level" select="$level" />
</xsl:call-template>
</xsl:template>
<xsl:template name="_tokenize-delimiters">
<xsl:param name="string" />
<xsl:param name="delimiters" />
<xsl:param name="level" />
<xsl:param name="last-delimit"/>
<xsl:variable name="delimiter"
select="substring($delimiters, 1, 1)" />
<xsl:choose>
<xsl:when test="not($delimiter)">
<!-- Sends individual attribute value for
processing
-->
<xsl:call-template name="process-includeExclude"
<xsl:with-param
name="currentExsite"><xsl:value-of
select="$string"/></xsl:with-param>
</xsl:call-template>
</xsl:when>
<!-- process string until all tokens are
separated
-->
<xsl:when test="contains($string, $delimiter)">
<xsl:if test="not(starts-with($string,
$delimiter))">
<xsl:call-template
name="_tokenize-delimiters">
<xsl:with-param name="string"
select="substring-before($string, $delimiter)" />
<xsl:with-param name="delimiters"
select="substring($delimiters, 2)" />
<xsl:with-param name="level"
select="$level" />
</xsl:call-template>
</xsl:if>
<xsl:call-template
name="_tokenize-delimiters">
<xsl:with-param name="string"
select="substring-after($string, $delimiter)" />
<xsl:with-param name="delimiters"
select="$delimiters" />
