Hello Johannes, hello Scott,

many thanks for your quick replies!

It turned out that somehow the linking-element

<link xlink:href=""someURL">hotlink</link>

is internally converted to ulink, that's what the debugging-code from Johannes told me.

So I modified my customization layer like that:

        <xsl:attribute-set name="xref.properties">
               <xsl:attribute name="color">
                       <!--<xsl:message>
                               <xsl:value-of select="concat('*** ',local-name(.))"/>"
                       </xsl:message>
                       <xsl:for-each select="@*">
                               <xsl:message>
                                       <xsl:value-of select="concat('### ',namespace-uri(.),' - ',local-name(.))"/>
                               </xsl:message>
                       </xsl:for-each>-->
                       <xsl:choose>
                               <xsl:when test="self::link and @linkend">yellow</xsl:when>
                               <xsl:when test="self::ulink">green</xsl:when>
                               <xsl:when test="self::xref and @linkend">orange</xsl:when>
                               <xsl:when test="self::glossseealso and @otherterm">grey</xsl:when>
                               <xsl:otherwise>blue</xsl:otherwise>
                       </xsl:choose>
               </xsl:attribute>
       </xsl:attribute-set>

and it worked!

Now, of course I would love to know: why?

Anyway, many thanks for your help,

cheers,

Benno

Benno,

that's hard to say.
What about adding debug code like this to your xsl:attribute element:

           <xsl:message>
               <xsl:value-of select="concat('*** ',local-name(.))"/>                
           </xsl:message>
           <xsl:for-each select="@*">
               <xsl:message>
                   <xsl:value-of select="concat('### ',namespace-uri(.),' - ',local-name(.))"/>
               </xsl:message>
           </xsl:for-each>

This should give you sufficient information to diagnose why it doesn't work as expected.

Regards

Johannes

I am sorry, but I tried that in every possible constellation and with every xpath-expression known to man (me ;-) and it seems that every element and attribute can be resolved with the exeption of exactly the xlink:href-attribute.
Have a look at this:

<!-- macht die externen links in pdfs blau, xrefs grün, see also links in glossaries grau -->
  <xsl:attribute-set name="xref.properties">
      <xsl:attribute name="color">
          <xsl:choose>
                  <xsl:when test="self::link and @linkend">grey</xsl:when>
                  <xsl:when test="self::link and @xlink:href">blue</xsl:when>
                  <xsl:when test="self::xref and @linkend">green</xsl:when>
                  <xsl:when test="self::glossseealso and @otherterm">grey</xsl:when>
              <xsl:otherwise>black</xsl:otherwise>
          </xsl:choose>
      </xsl:attribute>
  </xsl:attribute-set>

What am I missing? Is it a namespace-problem with xlink: ? I put the namespace on top of my customization layer:


<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
      version="1.0"   xmlns:dc="http://purl.org/dc/elements/1.1/"
      xmlns:fo="http://www.w3.org/1999/XSL/Format"
      xmlns:xlink="http://www.w3.org/1999/xlink"
      exclude-result-prefixes="#default">

What is wrong?

Benno

Yes, correct. So the DocBook-5-Version would be as follows:

  <xsl:attribute-set name="xref.properties">
      <xsl:attribute name="color">
          <xsl:choose>
              <xsl:when test="self::d:link and @xlink:href">blue</xsl:when>
              <xsl:otherwise>inherit</xsl:otherwise>
          </xsl:choose>
      </xsl:attribute>
      <xsl:attribute name="text-decoration">
          <xsl:choose>
              <xsl:when test="self::d:link and @xlink:href">underline</xsl:when>
              <xsl:otherwise>inherit</xsl:otherwise>
          </xsl:choose>
      </xsl:attribute>
  </xsl:attribute-set>    

Thanks!

Johannes
