Re: [xsl] Nested lists

Rick,
Here is another way to look at the problem which identifies the first
potential list item and uses that to start an ordered list. The call-template
works it way forward outputting list items that have the same class value. I
did not go further to see how to use this for the sub lists.
<?xml
version="1.0" encoding="UTF-8"?>
<xsl:stylesheetxmlns:xsl="http://www.w3.org/1999/XSL/Transform"version="1.0";
xmlns:xhtml="http://www.w3.org/1999/xhtml";>
<xsl:outputindent="yes"/>
<xsl:strip-spaceelements="*"/>
<!-- turn off defaults -->
<xsl:templatematch="*|@*"/>
<!-- main start -->
<xsl:templatematch="/">
<xsl:apply-templates/>
</xsl:template>
<!-- push through all elements except p
with a list class -->
<xsl:templatematch="xhtml:html | xhtml:head | xhtml:body
| xhtml:p | xhtml:h2">
<xsl:elementname="{local-name()}">
<xsl:copy-ofselect="@*"/>
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
<!-- this is a list item -->
<xsl:templatematch="xhtml:p[contains(@class , 'list')]">
<xsl:choose>
<!--
first list item -->
<xsl:whentest="preceding-sibling::*[1][not(contains(@class
, 'list'))]">
<xsl:elementname="ol">
<xsl:call-templatename="look-forward">
<xsl:with-paramname="first"select="."/>
<xsl:with-paramname="here"select="."/>
</xsl:call-template>
</xsl:element>
</xsl:when>
<!-- not first list item -->
<xsl:otherwise/>
</xsl:choose>
</xsl:template>
<!-- that template looks
forward one at a time on the p to extract and output the list items -->
<xsl:templatename="look-forward">
<xsl:paramname="first"/>
<xsl:paramname="here"/>
<xsl:choose>
<xsl:whentest="$here/self::xhtml:p[contains(@class , 'list')] and
$first/@class = $here/@class">
<xsl:elementname="li">
<xsl:copy-ofselect="@*"/>
<xsl:apply-templatesselect="$here/node()"/>
</xsl:element>
<xsl:call-templatename="look-forward">
<xsl:with-paramname="first"select="$first"/>
<xsl:with-paramname="here"select="$here/following-sibling::*[1]"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise/>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>

Hi Rick,

Compared to the pain using XSLT1 for a task which XSLT2 can easily
handle,
the pain you have to go through if you are forced to change a nice
working
XSLT2 solution down to XSLT1 is a real PITA.

But anyhow, I know that
sometimes we are forced to do ugly stuff. I would
not be trying to use xsl:key
for that problem, as keys are more of an index
across a full document and in
your situation everything depends on the order
of elements. In XSLT2 you would
use xsl:for-each-group, which in XSLT1
sometimes can be kind-of replicated by
"tree walking"
<http://www.dpawson.co.uk/xsl/sect2/N4486.html#d5510e1105>.

As
in your example the same class attribute value maybe used for a level 1
or
level 2 list item, it might also be a good idea to do some preprocessing,
because otherwise some XPaths may become really long. I guess I would try to
separate the logic of finding the correct list item level from the step of
adding the required <ul>.

Good luck,

- Michael
