Kanthi,
The following produces the output you specify, using Saxon 6.2.2. It
differs from your XSL only in that
- the grpTypes string must start with a space, or the 'Mystery'
titles appear without a heading.
- I have added a space before the first
<xsl:value-of select="../Title"/> to get the required indent.
You seem to have either
* a bug in your XSLT processor which gets the test involving
'preceeding' wrong
* what you posted is not what you are running
* there is another template matching "Type" elsewhere in your
stylesheet which is preventing this one being triggered.
Perhaps you are over-simplifying your problem? I am guessing that you
may in fact want to do grouping/sorting on XML which is not in the
required order, i.e. the 'Horror' titles do not in fact appear
consecutively.
Stylesheet:
<xsl:variable name="grpTypes" select="' Mystery Horror'"/>
<xsl:template match="text()"/>
<xsl:template match="Type">
<xsl:choose>
<xsl:when test="contains($grpTypes, concat(' ', .))">
<xsl:if test="not(. = preceding::Type)">
<xsl:value-of select="concat(., '
')"/>
</xsl:if>
<xsl:text> </xsl:text><xsl:value-of select="../Title"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="../Title"/>
</xsl:otherwise>
</xsl:choose>
<xsl:text>
</xsl:text>
</xsl:template>
Output:
Chocolat
Billy
Mystery
Ellen Brokovich
Pelican Brief
Horror
Nightmare on Elm Street
Blair Witch Project
The Emperor's Groove
Toy Story
