Re: [docbook-apps] line numbering with xsltproc

["Bob Stayton" <bobs@sagehill.net>]

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 &#xA;, 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
