Re: TOC indents in XHTML?

<xsl:for-each select="ancestor::part">
    <xsl:text>&#160;&#160;</xsl:text>
</xsl:for-each>

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? :-)
