[xsl] [newbie] What is the problem with preceding::simplesect/@id ?

[Thomas Dupouy <moz at gmx dot fr>]

Hello,
I'm new to xslt, and there are some problems I cannot understand. This
one : two navigation links following "simple sections" of an XML
docbook.
<!-- ----------------------- start ---------------------- -->
<tr><td align="left" nowrap="0">
Previous:&#160;
 <a>
  <xsl:attribute name="href">
   <xsl:text>romans.php?book=</xsl:text>
   <xsl:value-of select="$filename"/>
   <xsl:text>&amp;section=</xsl:text>
   <xsl:value-of select="preceding::simplesect/@id"/>
  </xsl:attribute>
  <xsl:value-of select="preceding::simplesect/title"/>
 </a>	
</td><td align="right" nowrap="0">
Next:&#160;
 <a>
  <xsl:attribute name="href">
   <xsl:text>romans.php?book=</xsl:text>
   <xsl:value-of select="$filename"/>
   <xsl:text>&amp;section=</xsl:text>
   <xsl:value-of select="following::simplesect/@id"/>
  </xsl:attribute>
  <xsl:value-of select="following::simplesect/title"/>
 </a>
<!-- ----------------------- end ---------------------- -->
The problem is that if the "Next" link go well to the following
simplesect, and through chapters, the "Previous" link always give the
first simplesect of the current chapter, instead of just the preceding
simplesect. I'm using PHP4+Sablotron if it makes a difference.

Thanks in advance for your solutions.

Regards,
