Subject: [xsl] Problem implementing grouping and sorting together From: Gary Bartlett <gary_a_bartlett@xxxxxxxxx> Date: Tue, 16 Oct 2001 19:30:03 -0700 (PDT) |
Greetings, I have a problem where I need to group elements and then sort each group and finally group the sorted elements for display purposes (to place a specific number of elements per row). Here is the approach that I have taken. I appreciate any pointers or suggestions as to how I can get the sorting portion to work. The first grouping is accomplished with a for-each with a select "distinct" similar to the following: //foo[not(.=preceding::foo)] Inside the body of the for-each, I call a template (name=processGroup) passing the distinct value as a parameter. The processGroup template creates a variable ($prices) containing all of the elements matching the value passed in the parameter. I then use a technique that I found documented on the Jenni site to perform the second set of grouping. This includes two apply-templates, the first with: select="$prices[position() mod $nbrPerLine = 1]" and the second with select=". | following-sibling::price[position() < $nbrPerLine]" This works great - except that now I cannot come up with a way to implement the sort. I have tried an additional apply-templates with a sort from within the template that creates the $prices variable. This sorts the elements - but then I can't figure a way to pass this "set" to the template that contains the "position() mod " style select above (the template is receiving the sorted elements one at a time - which doesn't quite cut it). Thanks in advance for any help with this. Gary Bartlett __________________________________________________ Do You Yahoo!? Make a great connection at Yahoo!
