Re: [xsl] blockQuotes to blockQuote p p

Jim,

A couple of years ago at the Extreme conference I had the honor of hanging out with Mike Kay, who told us about features slated for XSLT 2.0 and challenged us with a few "advanced" XSLT problems.

One of them is effectively yours. The source:

<?xml version="1.0" encoding="iso-8859-1"?>
<!-- from Hart's Rules for Compositors, 39th edition, OUP -->
<rules>
<p>The following should appear in italic:</p>
<bullet>Titles of operas, ballets, song cycles, symphonic poems,
  oratorios, overtures.</bullet>
<bullet>Abbreviated volume indications: <i>pp</i>, <i>mf</i>, etc.
  (these are always lower case).</bullet>
<p>The following should appear in roman, with single quotation marks:</p>
<bullet>Titles of single songs</bullet>
<bullet>Popular names of works, e.g. the 'Jupiter' Symphony</bullet>
<bullet>Phrases denoting tempo marks (unless used as the name of
a movement): 'allegro non troppo', 'più tranquillo'.</bullet>
<p>The following should appear in roman without quotation marks:</p>
<bullet>Musically descriptive titles: Piano Sonata Op. 111, Finale.</bullet>
<bullet>Technical terms and names of instruments: andante, cor anglais,
forte, organum, sh&#x0113;ng, vihuela.</bullet>
</rules>

The problem: convert to HTML, grouping adjacent <bullet> nodes as <li> elements inside <ul> wrappers. (See it's the same, isn't it.)

There are actually at least two solutions that are fairly straightforward. One is a grouping solution (key the bullets to the first preceding sibling bullet whose immediate preceding element isn't a bullet; let those bullets pick up the others). The other is a forward-walking solution, like what you're trying. This is my version of that solution to Mike's problem:

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet
  version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:output method="html" encoding="iso-8859-1"/>

<xsl:template match="rules">
  <div>
    <xsl:apply-templates/>
  </div>
</xsl:template>

<xsl:template match="p">
  <xsl:copy-of select="."/>
</xsl:template>

<xsl:template match="bullet">
  <xsl:if test="not(preceding-sibling::*[1][self::bullet])">
    <ul>
      <li><xsl:apply-templates/></li>
      <xsl:apply-templates mode="in-list"
        select="following-sibling::*[1][self::bullet]" />
    </ul>
  </xsl:if>
</xsl:template>

<xsl:template match="bullet" mode="in-list">
  <li><xsl:apply-templates/></li>
  <xsl:apply-templates mode="in-list"
    select="following-sibling::*[1][self::bullet]"/>
</xsl:template>

</xsl:stylesheet>

I think you'll see it's basically what you're trying to do, only cleaned up and using a mode instead of named templates.

The output (just to show it runs):

<div>
   <p>The following should appear in italic:</p>
   <ul>
      <li>Titles of operas, ballets, song cycles, symphonic poems,
           oratorios, overtures.
      </li>
      <li>Abbreviated volume indications: pp, mf, etc.
           (these are always lower case).
      </li>
   </ul>
   <p>The following should appear in roman, with single quotation marks:</p>
   <ul>
      <li>Titles of single songs</li>
      <li>Popular names of works, e.g. the 'Jupiter' Symphony</li>
      <li>Phrases denoting tempo marks (unless used as the name of
         a movement): 'allegro non troppo', 'pi&ugrave; tranquillo'.
      </li>
   </ul>
   <p>The following should appear in roman without quotation marks:</p>
   <ul>
      <li>Musically descriptive titles: Piano Sonata Op. 111, Finale.</li>
      <li>Technical terms and names of instruments: andante, cor anglais,
         forte, organum, sh&#275;ng, vihuela.
      </li>
   </ul>
</div>

I hope it helps,
Wendell
