Re: [docbook-apps] Epub and Saxon

Hi,

I just ran into the same issue describe in this email conversation(from May 2013). Looks to me that there was no new release of the XSL sheets since May 2013 (according to http://sourceforge.net/projects/docbook/files/docbook-xsl/) is this planned for the near future?

Best regards, Lars

It is a bug in the epub/docbook.xsl stylesheet file.  
This template:

 

<xsl:template match="d:author|d:corpauthor" 
mode="opf.metadata">

 

creates the dc:creator element and tries to add an attribute 
named "opf:file-as" by calling the template named 
'person.name.last-first'.  However, that template generates an HTML 
<span> element, and you cannot put an element into an attribute 
value.  The solution is to take the text value of the that template 
call:

 

  <xsl:template match="d:author|d:corpauthor" 
mode="opf.metadata">
    <xsl:variable 
name="n">
      <xsl:call-template 
name="person.name">
        
<xsl:with-param name="node" select="."/>
      
</xsl:call-template>
    
</xsl:variable>
    <xsl:element 
name="dc:creator">
      <xsl:attribute 
name="opf:file-as">
        
<xsl:variable 
name="attvalue">
          
<xsl:call-template 
name="person.name.last-first">
            
<xsl:with-param name="node" 
select="."/>
          
</xsl:call-template>
        
</xsl:variable>
        
<xsl:value-of select="$attvalue"/>
      
</xsl:attribute>
      <xsl:value-of 
select="normalize-space(string($n))"/>
    
</xsl:element>
  </xsl:template>

 

I'll fix this in the source, and you can use this in your 
customization layer.

It is the author element in info that triggers the problem:

      
<author>
        
<personname>
          
<firstname>Marcel</firstname>
          
<surname>Tromp</surname>
        
</personname>
      
</author>

If I use an empty authorgroup, no errors are generated. The error I showed 
before is generated twice: once for firstname, once for lastname.

Hi Marcel,

  
Can you determine exactly which element in info is 
  triggering that error?  Perhaps comment out all but one element at a 
  time?

Hi,

  
 

  
I am setting up flow to generate epub using 1.78.1, but will use Saxon 
  instead of xsltproc.

  
 

  
With xsltproc, document converts without any warnings/errors, but Saxon 
  throws recoverable errors:

  
 

  
Recoverable error
at xsl:attribute 
  on line 211 of 
  file://work/mtools/docbook-xsl-ns/dev/xhtml-1_1/inline.xsl:
  
  Cannot write an attribute node when no element start tag is open
Writing 
  OEBPS/content.opf

  
This seems to be caused by adding the author data to content.opf in line 
  260 of epub/docbook.xsl:

  
 

  
     
  <xsl:apply-templates select="/*/*[contains(name(.), 
  'info')]/*"
                                 
  mode="opf.metadata"/>

  
Although the generated file seems ok, the error output will be 
  problematic/confusing for users.

  
 

  
Is there a way to suppress these errors, or even better, prevent them 
  from happing?
