preceding-sibling::chapter[nummer]

["Lily Galle" <lily.galle@gmx.net>]

Hi,

I have the following code in my xsl Stylesheet: 

  <xsl:attribute-set name="header.table.properties">
    <xsl:attribute name="background-color">
      <xsl:choose>       
        <xsl:when test="preceding-sibling::chapter[2]">green</xsl:when>
        <xsl:when test="preceding-sibling::chapter[1]">red</xsl:when>      
        <xsl:otherwise>blue</xsl:otherwise>
      </xsl:choose>
    </xsl:attribute>
… …
  </xsl:attribute-set>

In the output file the chapter one does not have red color in header, but blue. Chapter 2 does not have green color, but red. Why?

Is chapter ein “preceding-sibling” node of header.table? Where can I see this? I think it is not in DocBook-Scheama. I checked for example the docBook Definitive guide (http://www.docbook.org/tdg5/en/html/book.html ). It does not show this. 

Thanks for any help!

Lily
