RE: for-each and summing based on group
First read up about standard grouping techniques such as Muenchian grouping at http://www.jenitennison.com/xslt/grouping Computing a subtotal for each group is then a minor variant of the technique: instead of merely iterating over the items in the group using xsl:for-each, you can assign the node-set comprising the group to a variable, and then sum over that using the sum() function. Like all grouping problems, it's much easier in 2.0: <xsl:for-each-group select="rows" group-by="columnA"> <xsl:apply-templates select="current-group()"/> <subtotal><xsl:value-of select="sum(current-group()/columnB)"/></subtotal> </xsl:for-each-group> Michael Kay http://www.saxonica.com/ > -----Original Message----- > From: dsk [mailto:dmitrik@xxxxxxxxxxxxxx] > Sent: 05 January 2005 04:09 > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Subject: for-each and summing based on group > > > within a for-each there might be various sets of values which > produce the > following grid, where val is equal to a number > > a val val val > a val val val > a val val val > b val val val > b val val val > c val val val > c val val val > > what is the best way to insert a sum line for the first > column a, one for b, and one for c. > > is a nested for each needed? or checking to see if the > following value is > not equal to the preceding, then then summing? > > thanks, > Dmitri > > --- > Outgoing mail is certified Virus Free. > Checked by AVG anti-virus system (http://www.grisoft.com). > Version: 6.0.802 / Virus Database: 545 - Release Date: 11/26/2004
