That highlights very closely to what I have done; although I like the elegance the author has used. That is the next task is to clean up my XSLT file so that it is much easier to read.

I have been playing with recursive template calls all morning, and thus far this is what I have arrived at is the following: <!-- This template matches against a planning record entry in the plan for every part XML document. --> <xsl:template match="record"> <xsl:call-template name="forLoopYear"> <xsl:with-param name="start"> <xsl:value-of select="$curYear"/> </xsl:with-param> <xsl:with-param name="end"> <xsl:value-of select="$curYear+(-4)"/> </xsl:with-param> </xsl:call-template> </xsl:template> <!-- This template handles iterating over a start and end year values stepping by 1 year. --> <xsl:template name="forLoopYear"> <xsl:param name="start"/> <xsl:param name="end" /> <xsl:if test="$start != $end"> <xsl:value-of select="$start"/><xsl:text> </xsl:text> <xsl:call-template name="forLoopMonth"> <xsl:with-param name="month">1</xsl:with-param> <xsl:with-param name="year"> <xsl:value-of select="$start"/> </xsl:with-param> </xsl:call-template> <xsl:call-template name="forLoopYear"> <xsl:with-param name="start"> <xsl:value-of select="$start+1"/> </xsl:with-param> <xsl:with-param name="end"> <xsl:value-of select="$end"/> </xsl:with-param> </xsl:call-template> </xsl:if> </xsl:template> <!-- This template handles iterating over months 1 Through 12, looks up the data from the XML Document and if it exists, displays it; Otherwise outputs a 0 for the month/year. --> <xsl:template name="forLoopMonth"> <xsl:param name="month"/> <xsl:param name="year"/> <xsl:if test="$month <= 12"> <xsl:for-each select="usage/details/detail"> <xsl:if test="year = $year"> <xsl:if test="month = $month"> <xsl:value-of select="quantity"/><xsl:text> </xsl:text> </xsl:if> </xsl:if> </xsl:for-each> <xsl:call-template name="forLoopMonth"> <xsl:with-param name="month"> <xsl:value-of select="$month+1"/> </xsl:with-param> <xsl:with-param name="year"> <xsl:value-of select="$year"/> </xsl:with-param> </xsl:call-template> </xsl:if> </xsl:template> First, this a good approach or is there a better way? Secondly, how do I handle the scenario where I do not find the node /usage/details/detail with the specified year/month to output a standard 0 value?
