Re: [xsl] Generating an HTML with a navigation menu and a fu

Hi Shlomi,

First some remarks about your stylesheet:

<xsl:template match="comparison">
    <xsl:apply-templates select="//comparison/contents/section">

Don't do this: it will scan the complete input file into the deepest level,
searching for comparison elements. The template is already in the
comparison element context, so it's better to use:

    <xsl:apply-templates select="contents/section">

<xsl:with-param name="toc" value="1"/>

xsl:with-param takes a select, not a value attribute.
That's why, in the corresponding template, <xsl:when test="$toc = 1">
is never reached. Anyway, using params here is not necessary,
it's much easier to use a different mode (see below).

Here's a reworked version of compare-ml.xsl, it will generate a 
table of contents just like the one in comparison.html:

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet version="1.0"
 xmlns="http://www.w3.org/1999/xhtml";
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
 >

 <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"
  doctype-public="-//W3C//DTD XHTML 1.0 Strict//EN"
  doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";
  />

 <xsl:key name="impl" match="/comparison/meta/implementations/impl" use="@id"/>

 <xsl:template match="/comparison">
  <html xmlns="http://www.w3.org/1999/xhtml";>
   <head>
    <title><xsl:value-of select="contents/section[@id='main']/title"/></title>
    <style type="text/css">
     h2 { background-color : #98FB98; /* PaleGreen */ }
     h3 { background-color : #FFA500; /* Orange */ }
     table.compare 
     { 
       margin-left : 1em; 
       margin-right : 1em; 
       width: 90%;
       max-width : 40em;
     }
     .compare td 
     { 
       border-color : black; border-style : solid ; border-width : thin;
       vertical-align : top;
       padding : 0.2em;
     }
     ul.toc
     {
       list-style-type : none ; padding-left : 0em;
     }
     .toc ul
     {
       list-style-type : none ; 
       padding-left : 0em; 
       margin-left : 2em;
     }
     .expl
     {
       border-style : solid ; border-width : thin;
       background-color : #E6E6FA; /* Lavender */
       border-color : black;
       padding : 0.3em;
     }
     :link:hover { background-color : yellow }
    </style>
   </head>
   <body>
    <xsl:apply-templates select="contents"/>
   </body>
   <!--http://rafb.net/paste/results/lTurEi25.html-->
  </html>
 </xsl:template>

 <xsl:template match="contents">
  <xsl:apply-templates select="section"/>
 </xsl:template>

 <xsl:template match="section">
  <xsl:element name="h{count(ancestor-or-self::section)}">
   <a id="{@id}"></a>
   <xsl:value-of select="title"/>
  </xsl:element>
  <xsl:apply-templates select="expl"/>
  <xsl:if test="@id = 'main'">
   <ul>
    <xsl:apply-templates select="section" mode="toc"/>
   </ul>
  </xsl:if>
  <xsl:apply-templates select="section"/>
  <xsl:apply-templates select="compare"/>
 </xsl:template>

 <xsl:template match="section" mode="toc">
  <li>
   <a href="#{@id}"><xsl:value-of select="title"/></a>
   <xsl:if test="section">
    <ul>
     <xsl:apply-templates select="section" mode="toc"/>
    </ul>
   </xsl:if>
  </li>
 </xsl:template>

 <xsl:template match="expl">
  <p class="expl">
   <xsl:value-of select="."/>
  </p>
 </xsl:template>

 <xsl:template match="compare">
  <table class="compare">
   <xsl:apply-templates select="s"/>
  </table>
 </xsl:template>

 <xsl:template match="s">
  <tr>
   <td class="sys"><xsl:value-of select="key('impl', @id)/name"/></td>
   <td class="desc"><xsl:value-of select="."/></td>
  </tr>
 </xsl:template>

</xsl:stylesheet>
