Re: [docbook-apps] line numbering with xsltproc

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>

Subject: [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
