Hi all,
Does anyone has experience on assigning ranking to sorted number using xslt? Any help/reference given is very much appreciated. Thanks.
XML File
================================
<countries>
<country><name>UK</name><number>55</number></country>
<country><name>US</name><number>40</number></country>
<country><name>Singapore</name><number>55</number></country>
<country><name>China</name><number>20</number></country>
<country><name>Taiwan</name><number>20</number></country>
<country><name>Canada</name><number>70</number></country>
<country><name>Japan</name><number>70</number></country>
</countries>
Intended OUTPUT - ascending sort
================================
Rank - Number - Country
1 - 20 - China
1 - 20 - Taiwan
2 - 40 - US
3 - 55 - Singapore
3 - 55 - UK
4 - 70 - Canada
4 - 70 - Japan
XSLT
================================
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" />
<xsl:key name="sort" match="country" use="number"/>
<xsl:variable name="list" select="countries/country[generate-id(.) = generate-id(key('sort', number))]"/>
<xsl:template match="/">
<xsl:call-template name="process-list">
<xsl:with-param name="rank" select="1" />
<xsl:with-param name="position" select="1" />
<xsl:with-param name="counter" select="0" />
</xsl:call-template>
</xsl:template>
<xsl:template name="process-list">
<xsl:param name="rank" />
<xsl:param name="position" />
<xsl:param name="counter" />
<xsl:choose>
<!-- process new number -->
<xsl:when
test="$counter = count($list[number =
$list[$rank]/number]) - 1">
<xsl:apply-templates select="$list[$rank]">
<xsl:with-param name="rank" select="$rank" />
</xsl:apply-templates>
<xsl:call-template name="process-list">
<xsl:with-param name="rank" select="$rank" />
<xsl:with-param name="position" select="$position + 1" />
<xsl:with-param name="counter" select="1" />
</xsl:call-template>
</xsl:when>
<!-- process the rest of the current number -->
<xsl:otherwise>
<xsl:apply-templates select="countries/country[number =
$list[$rank]/number][$counter + 1]">
<xsl:with-param name="rank" select="$rank" />
</xsl:apply-templates>
<xsl:choose>
<!-- goto next number -->
<xsl:when test="$counter = count(countries/country[number =
$list[$rank]/number])">
<!-- test if there are more numbers -->
<xsl:if test="$rank < count($list)">
<xsl:call-template name="process-list">
<xsl:with-param name="rank" select="$rank + 1" />
<xsl:with-param name="position" select="$position" />
<xsl:with-param name="counter" select="0" />
</xsl:call-template>
</xsl:if>
</xsl:when>
<!-- goto next in this number -->
<xsl:otherwise>
<xsl:call-template name="process-list">
<xsl:with-param name="rank" select="$rank" />
<xsl:with-param name="position" select="$position + 1" />
<xsl:with-param name="counter" select="$counter + 1" />
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="country">
<xsl:param name="rank" />
<xsl:value-of select="$rank" />
<xsl:text> - </xsl:text>
<xsl:value-of select="number" />
<xsl:text> - </xsl:text>
<xsl:value-of select="name" />
<xsl:text>; </xsl:text>
</xsl:template>
</xsl:stylesheet>
OUTPUT from Above XSLT
Problem - I am not able to sort the number in ascending/descending before assigning the ranking.
================================
1 - 55 - UK;
1 - 55 - Singapore;
2 - 40 - US;
3 - 20 - China;
3 - 20 - Taiwan;
4 - 70 - Canada;
4 - 70 - Japan;
Thank you in advance,
