RE: [xsl] TOC indents in XHTML?

[Don Bruey <dbruey@xxxxxxxxxxxxxxxxxxxxx>]

You can write a named template that accepts as a parameter the value of your
$level variable.  Have it create the output you want for a single
indentation, then call itself recursively for each remaining level.
Probably you can find some similar things if you dig through the FAQ.
Something like this:

<xsl:template name="indent">
	<xsl:param name="level"/>
	<xsl:if test="$level &gt; 0" >
  		<!-- put your output here for one indentation level -->
		<xsl:call-template name="indent">
   			<xsl:with-param name="level" select="$level - 1" />
		</xsl:call-template>
	</xsl:if>
</xsl:template>

Written on the fly, might need a little work. Good luck.

Don

Subject: [xsl] TOC indents in XHTML?


I have made a stylesheet to convert an XML document format to XHTML.
Documents conforming to the DTD is divided into a recursive <part> element.
For each level of depth (nested <part> elements) I want another two spaces
in the TOC, like this:

1 The first chapter
  1.1 Some sub-section of the first chapter
  1.2 Another sub-section
2 Another chapter
  2.1 A sub-section of the second chapter
    2.1.1 A sub-sub-section.
    2.1.2 Another sub-sub-section.

Currently, I have a template for the indents that looks like this:

  <xsl:template name="toc-indent">
    <xsl:variable name="level" select="count(ancestor::part)"/>
    <xsl:choose>
      <xsl:when test="$level=0"><xsl:text
disable-output-escaping="yes"></xsl:text></xsl:when>
      <xsl:when test="$level=1"><xsl:text
disable-output-escaping="yes">&amp;nbsp;&amp;nbsp;</xsl:text></xsl:when>
      <xsl:when test="$level=2"><xsl:text
disable-output-escaping="yes">&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;</xsl:
text></xsl:when>
      <xsl:when test="$level=3"><xsl:text
disable-output-escaping="yes">&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;n
bsp;&amp;nbsp;</xsl:text></xsl:when>
      <xsl:when test="$level=4"><xsl:text
disable-output-escaping="yes">&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;n
bsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;</xsl:text></xsl:when>
      <xsl:when test="$level=5"><xsl:text
disable-output-escaping="yes">&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;n
bsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;</xsl:text></xsl:when>
      <xsl:otherwise><xsl:text
disable-output-escaping="yes">&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;n
bsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;</xsl:text></xsl:other
wise>
    </xsl:choose>
  </xsl:template>

It works, but it's not smart and far from beautiful. There is a better way
to do it, isn't it? :-)
