[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Re: Sorting and gouping
 Ronald's code was extremely helpful for me. My problem was somewhat more
complicated. I'm terribly sorry for I forgot to emphasize that I needed
to enclose each group into tags (say DIV) i.e. <DIV id="...">
group_of_item_elements </DIV>.
The problem is one can't create starting and ending tags in different
conditional clauses (error: "End tag 'xsl:when' does not match the start
tag 'DIV'" or so). To overcome this obstacle I generate DIV tags via
<xsl:text> with output escaping disabled. Ronald's code with this patch
follows:
XML:
<?xml version="1.0"?>
<list>
<item at="d">d</item>
<item at="e">e</item>
<item at="i">i</item>
<item at="k">k</item>
<item at="l">l</item>
<item at="a">a</item>
<item at="b">b</item>
<item at="c">c</item>
<item at="j">j</item>
<item at="f">f</item>
<item at="g">g</item>
<item at="h">h</item>
<item at="a">a</item>
<item at="b">b</item>
<item at="c">c</item>
<item at="f">f</item>
</list>
XSL:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html"/>
<xsl:param name="group">5</xsl:param> <!-- grouping size-->
<xsl:variable name="items" select="count(//item)"/> <!-- total number
of items-->
<xsl:template match="list">
<HTML>
<BODY>
<xsl:apply-templates select="item">
<xsl:sort select="@at" order="ascending"/>
</xsl:apply-templates>
</BODY>
</HTML>
</xsl:template>
<xsl:template match="item">
<xsl:choose>
<xsl:when test="position() mod $group =1">
<!-- Begin new group with gn = group # -->
<xsl:variable name="gn" select="concat('g', (position() + 4) div
5)"/>
<!-- DIV id="g#" -->
<xsl:text disable-output-escaping="yes"><DIV id="</xsl:text>
<xsl:value-of select="$gn"/><xsl:text
disable-output-escaping="yes">"></xsl:text>
<p><xsl:value-of select="position()"/>
<xsl:apply-templates/></p>
</xsl:when>
<xsl:when test="position() mod $group =0">
<!-- End group -->
<p><xsl:value-of select="position()"/>
<xsl:apply-templates/></p>
<!-- /DIV -->
<xsl:text
disable-output-escaping="yes"></DIV></xsl:text><hr />
</xsl:when>
<xsl:when test="not(position() mod $group =0) and position() =
$items">
<!-- last item in sorted list-->
<p><xsl:value-of select="position()"/>
<xsl:apply-templates/></p>
<!-- /DIV -->
<xsl:text disable-output-escaping="yes"></DIV></xsl:text>
</xsl:when>
<xsl:otherwise>
<p><xsl:value-of select="position()"/>
<xsl:apply-templates/></p>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
