Re: [docbook-apps] line numbering with xsltproc

I assumed you meant you wanted to number the lines 
in a programlisting, which has line break characters that are preserved during 
processing.  That's the kind of line numbering that the Xalan and Saxon 
extensions do, as well as the XSLT code that I suggested.

 

Your mail suggests you want to number lines of 
flowing paragraphs. That isn't something that can be done at the XSLT stage 
because line breaks are not yet established. It can only be done when the XSL-FO 
processor lays out the text and decides where to break lines. So you need an 
XSL-FO processor with an extension that can number lines of typeset material. As 
far as I know, only the Antenna House XSL Formatter (full version, not Lite) can 
add line numbering for paragraphs.

Hello 
  Bob,

  
 

  
thank you so much for 
  that great template and the immediate reply! It works. But there is still a 
  problem and I can’t find a solution:

  
Your choose condition 
  searches the “break” with the “
” entity. But in my case I often don’t 
  have any brakes and the result looks like this (blocks are 
  numbered):

So here is my 
  question: Could you explain me in which template the line breaks are set in 
  Docbook? Or do you know an other solution for this specific 
  problem?

Thank you very much for that great 
  support!

You try something like this in a 
  customization layer. It is not extensively tested. It recursively parses the 
  text node in a programlisting based on the line ending character 
, 
  inserts the line number, and recurses to the next 
  line.

  

  
 

  

  
 

  

  
<xsl:template 
  match="programlisting/text()">
  <xsl:call-template 
  name="line.numbering">
    <xsl:with-param 
  name="content" select="."/>
    <xsl:with-param 
  name="count" select="1"/>
  
  </xsl:call-template>
</xsl:template>

  

  
 

  

  
<xsl:template 
  name="line.numbering">
  <xsl:param name="content" 
  select="."/>
  <xsl:param name="count" 
  select="1"/>

  

  
 

  

  
  <xsl:number 
  value="$count" format="01 "/>

  

  
 

  

  
  
  <xsl:choose>
    <xsl:when test="contains($content, 
  '&#xA;')">
      <xsl:value-of 
  select="substring-before($content, 
  '&#xA;')"/>
      
  <xsl:text>&#xA;</xsl:text>

  

  
 

  

  
      
  <xsl:variable name="rest" select="substring-after($content, 
  '&#xA;')"/>
      <xsl:if 
  test="string-length($rest)">
        
  <xsl:call-template 
  name="line.numbering">
          
  <xsl:with-param name="content" 
  select="$rest"/>
          
  <xsl:with-param name="count" select="$count + 
  1"/>
        
  </xsl:call-template>
      
  </xsl:if>
    </xsl:when>
    
  <xsl:otherwise>
      <!-- we are done 
  -->
      <xsl:value-of 
  select="$content"/>
    </xsl:otherwise>
  
  </xsl:choose>
</xsl:template>

    [docbook-apps] line numbering with 
    xsltproc

    

    
 

    

    
Hello,

    
I am trying to insert 
    line numbering in my PDFs. I read that only 
    Saxon and Xalan provide that 
    function. Does anyone know how to implement line numbering in DocBook XML 
    files which are parsed with xsltproc?

I would be pleased to receive 
    any help concerning that problem. My extensive online search resulted in no 
    solution.

    
Regards,

    
Jan
