Subject: DOCBOOK-APPS: HTML filenames based on value of id attribute
Hi,
if you want your HTML filenames to be named by value of ID attribute (if
presenet), put following code in your customization layer. This feature
is present in DSSSL stylesheets, but still not in XSL stylesheets.
<xsl:param name="use.id.as.filename" select="1"/>
<xsl:template match="*" mode="chunk-filename">
<xsl:param name="recursive" select="false()"/>
<!-- returns the filename of a chunk -->
<xsl:variable name="ischunk"><xsl:call-template
name="chunk"/></xsl:variable>
<xsl:variable name="filename">
<xsl:call-template name="dbhtml-filename"/>
</xsl:variable>
<xsl:variable name="dir">
<xsl:call-template name="dbhtml-dir"/>
</xsl:variable>
<xsl:choose>
<xsl:when test="$ischunk='0'">
<!-- if called on something that isn't a chunk, walk up... -->
<xsl:choose>
<xsl:when test="count(parent::*)>0">
<xsl:apply-templates mode="chunk-filename" select="parent::*">
<xsl:with-param name="recursive" select="$recursive"/>
</xsl:apply-templates>
</xsl:when>
<!-- unless there is no up, in which case return "" -->
<xsl:otherwise></xsl:otherwise>
</xsl:choose>
</xsl:when>
<xsl:when test="not($recursive) and $filename != ''">
<!-- if this chunk has an explicit name, use it -->
<xsl:if test="$dir != ''">
<xsl:value-of select="$dir"/>
<xsl:text>/</xsl:text>
</xsl:if>
<xsl:value-of select="$filename"/>
</xsl:when>
<xsl:when test="not($recursive) and @id != '' and
$use.id.as.filename=1">
<!-- if this chunk has an explicit name in id attribute, use it
-->
<xsl:if test="$dir != ''">
<xsl:value-of select="$dir"/>
<xsl:text>/</xsl:text>
</xsl:if>
<xsl:value-of select="@id"/>
