Re: [docbook-apps] Change error message in output for missing xinclude?

I'm not sure if anyone mentioned this, but you 
could customize the scripting to handle unresolved xincludes. You create a 
template that matches on xi:include to output your own message.  The 
default message comes from this template that matches on any unrecognized 
element:

 

<xsl:template match="*">
  
<xsl:message>
    <xsl:text>Element 
</xsl:text>
    <xsl:value-of 
select="local-name(.)"/>
    <xsl:text> in namespace 
'</xsl:text>
    <xsl:value-of 
select="namespace-uri(.)"/>
    <xsl:text>' 
encountered</xsl:text>
    <xsl:if 
test="parent::*">
      <xsl:text> in 
</xsl:text>
      <xsl:value-of 
select="name(parent::*)"/>
    
</xsl:if>
    <xsl:text>, but no template 
matches.</xsl:text>
  </xsl:message>

 

  <span style="color: 
red">
    
<xsl:text>&lt;</xsl:text>
    <xsl:value-of 
select="name(.)"/>
    
<xsl:text>&gt;</xsl:text>
    
<xsl:apply-templates/>
    
<xsl:text>&lt;/</xsl:text>
    
<xsl:value-of select="name(.)"/>
    
<xsl:text>&gt;</xsl:text>
  
</span>
</xsl:template>

 

You could create a custom template like 
this:

 

<xsl:template match="xi:include">
  
<span class="EmptyInclude">
    
<xsl:text>Currently there is no Data available.</xsl:text>
  
</span>
</xsl:template>

 

and perhaps add an xsl:message if you need 
it.

Phil, David and Markus!

  
Thanks a lot for your help. I have adjusted my mother 
  file by adding the <xi:fallback> lines. Now the FO/PDF and HTML output 
  looks good and supplies proper information.

  
I agree to Markus' opinion, that adjusting the 
  scripting (which produces the referenced files) would be even more effective. 
  But we have no influence over it.

  
Best wishes,

  
Martin

This is very 
    easy:

<xi:include  href="intro.xml" xmlns:xi="http://www.w3.org/2001/XInclude">
  <xi:fallback>
    <para>Currently 
    there is no data available</para> 
    
  </xi:fallback>
</xi:include>
