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, '
')">
<xsl:value-of select="substring-before($content, '
')"/>
<xsl:text>
</xsl:text>
<xsl:variable name="rest" select="substring-after($content, '
')"/>
<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
