Hi,
I'm looking for some advice on refactoring the following ugliness, I think my problem is that I have an unpredictable range of dates to loop over - <xsl:variable name="today" select="xs:date('2008-02-01')"/> <xsl:variable name="one-year-cut-off" select="research:cutOffDate('P365D')"/> <xsl:variable name="six-months-cut-off" select="research:cutOffDate('P182D')"/> <xsl:variable name="three-months-cut-off" select="research:cutOffDate('P90D')"/> <xsl:variable name="one-month-cut-off" select="research:cutOffDate('P30D')"/> <xsl:variable name="one-week-cut-off" select="research:cutOffDate('P7D')"/> and so it's hard to build up a recursive template. The only thing I can think of is having a kind of pseudo array structure which I submit to the template as a nodeset otherwise I end up with this - <xsl:template name="group-by-date-created"> <xsl:for-each-group select="funding:Call" group-by="xs:date(cmn:Metadata/dcterms:created) < $one-year-cut-off"> <xsl:sort select="cmn:Metadata/dcterms:created" order="{$sort-order}" /> <xsl:choose> <xsl:when test="xs:date(cmn:Metadata/dcterms:created) > $one-year-cut-off"> <xsl:for-each-group select="current-group()" group-by="xs:date(cmn:Metadata/dcterms:created) < $six-months-cut-off"> <xsl:sort select="cmn:Metadata/dcterms:created" order="{$sort-order}" /> <xsl:choose> <xsl:when test="xs:date(cmn:Metadata/dcterms:created) > $six-months-cut-off"> <xsl:for-each-group select="current-group()" group-by="xs:date(cmn:Metadata/dcterms:created) < $three-months-cut-off"> <xsl:sort select="cmn:Metadata/dcterms:created" order="{$sort-order}" /> <xsl:choose> <xsl:when test="xs:date(cmn:Metadata/dcterms:created) > $three-months-cut-off"> <xsl:for-each-group select="current-group()" group-by="xs:date(cmn:Metadata/dcterms:created) < $one-month-cut-off"> <xsl:sort select="cmn:Metadata/dcterms:created" order="descending" /> <xsl:choose> <xsl:when test="xs:date(cmn:Metadata/dcterms:created) > $one-month-cut-off"> <xsl:for-each-group select="current-group()" group-by="xs:date(cmn:Metadata/dcterms:created) < $one-week-cut-off"> <xsl:choose> <xsl:when test="xs:date(cmn:Metadata/dcterms:created) > $one-week-cut-off"> <xsl:for-each-group select="current-group()" group-by="xs:date(cmn:Metadata/dcterms:created) <= $today"> <xsl:choose> <xsl:when test="xs:date(cmn:Metadata/dcterms:created) >= $one-week-cut-off"> <xsl:call-template name="current-group"> <xsl:with-param name="groupName" select="'this-week'"/> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:call-template name="current-group"> <xsl:with-param name="groupName" select="'one-week-?'"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:for-each-group> </xsl:when> <xsl:otherwise> <xsl:call-template name="current-group"> <xsl:with-param name="groupName" select="'one-week-plus'"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:for-each-group> </xsl:when> <xsl:otherwise> <xsl:call-template name="current-group"> <xsl:with-param name="groupName" select="'one-month-plus'"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:for-each-group> </xsl:when> <xsl:otherwise> <xsl:call-template name="current-group"> <xsl:with-param name="groupName" select="'three-months-plus'"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:for-each-group> </xsl:when> <xsl:otherwise> <xsl:call-template name="current-group"> <xsl:with-param name="groupName" select="'six-months-plus'"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:for-each-group> </xsl:when> <xsl:otherwise> <xsl:call-template name="current-group"> <xsl:with-param name="groupName" select="'one-year-plus'"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:for-each-group> Any advice would be much appreciated, Cheers, Fraser
