Here is a template that returns the string at the offset passed in the index
param. An empty string is returned if the index is larger than the number of
items in the list. If the index is less than 1 it always returns first element.
<xsl:variable name="ValuesString" select="'10,20,30,40,50'"/>
<xsl:variable name="ValueDelimiter" select="','"/>
<xsl:variable name="Index" select="4"/>
<xsl:template match="/">
<xsl:variable name="item-at-index">
<xsl:call-template name="getByIndex">
<xsl:with-param name="index" select="$Index"/>
<xsl:with-param name="list" select="$ValuesString"/>
<xsl:with-param name="delim" select="$ValueDelimiter"/>
</xsl:call-template>
</xsl:variable>
<selected>
<xsl:value-of select="$item-at-index"/>
</selected>
</xsl:template>
<xsl:template name="getByIndex">
<xsl:param name="list"/>
<xsl:param name="index" select="1"/>
<xsl:param name="delim" select="','"/>
<xsl:choose>
<xsl:when test="string($list) != '' and number($index) > 1">
<!-- recurse discarding the top comma separated element
until there are no more commas, or we reach the
correct index -->
<xsl:call-template name="getByIndex">
<xsl:with-param name="index" select="$index - 1"/>
<xsl:with-param name="list" select="substring-after($list,$delim)"/>
<xsl:with-param name="delim" select="$delim"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<!-- if there are remaining commas then truncate the
string, otherwise just return what remains of
the list (zero or one elements) -->
<xsl:choose>
<xsl:when test="contains($list,$delim)">
<xsl:value-of select="substring-before($list,$delim)"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$list"/>
</xsl:otherwise>
</xsl:choose>
</xsl:otherwise>
</xsl:choose>
</xsl:template>

Subject: [xsl] to access a particular token in a comma separated string
by specifying a numerical value ?
How can I access a particular token in a comma separated string by specifying a
numerical value for the token number using XSL?
Assuming, my xsl:variable or xsl:parameter holds a string with comma-separated
values as shown below:
<xsl:variable name="ValuesString" select="'10,20,30,40,50'"/>
How would I go about finding a way to pick out the value specified by a count
that maps another variable/parameter.
Open to Ideas :)
Thanks,
Abhishek
