Subject: [xsl] Counting Duplicates in XSLT 2.0 From: Felix Breuer <felix@xxxxxxxxxx> Date: Wed, 30 Aug 2006 00:58:10 +0200 |
Hello everyone! I have an element with a large number of complex child-elements and for each child I want to know how many duplicates there are (considering two elements as identical iff they are deep-equal). Initially I thought <for-each-group group-by="."> ... to be the way to go, but then I noticed in the XSLT 2.0 spec that the value of the group-by expression is atomized after evaluation. So, how do I go about this task? Going further: * How can I remove all the duplicates of a given child element, retaining exactly one copy? * How can I keep exactly one copy iff the number of identical copies is odd, and remove all copies iff the number is even? Thanks, Felix
