AW: [docbook-apps] an expression / a parameter within <xsl:include href='$xxx'/> not allowed?

Hi Bob,

thank you for your answer. In the meantime I found
several conversations which clarified the matter. So I went in the direction XML
catalog as you are suggesting. 

 

Although
did I not find that fact in the XSL specification.

 

Best

We all wish that you could put
variable references in the href value for xsl:include, but alas, it is not
allowed.  The basic problem is that all includes are processed before any
variables are processed, so your variable will have no value.

 

One way to achieve selection at
runtime is to use XML catalogs to map a fixed href (no variables) to a
location. Then you can select a different catalog at runtime to choose a
different location.

Hi,

 

until
now I used 

 

    <xsl:include
href="../temp/titlepageFO.xsl"/>

 

and it worked
fine. As I generalize my scripts from now on I have to use an expression 

to build the href
value. 

 

My understanding
of the XLS specification is, that expressions are allowed within an href
attribute.

 

I tried

 

    <xsl:include
href="$baseDir/temp/titlepageFO.xsl"/>

    <xsl:include href="{$baseDir/temp/titlepageFO.xsl}"/>

    <xsl:include href="{$baseDir}/temp/titlepageFO.xsl"/>

 

but none of these
variants works nor with XALAN neither with SAXON. (The $baseDir parameter works
surely, because it delivers the right value in another expression).

 

Has anybody an
idea?

 

Best Regards
