Subject: [xsl] Trying to sort node set while tagging specific nodes in it From: Stan <sgd@xxxxxxxxxxxx> Date: Wed, 27 Jul 2005 11:20:25 -0400 |
<root> <rec> <name>z</name> <year>2004</name> </rec> <rec> <name>z</name> <year>2005</year> </rec> <rec> <name>a</name> <year>2002</year> </rec> <rec> <name>a</name> <year>2003</year> </rec> </root>
<root> <rec> <name tag="latest">a</name> <year>2003</year> </rec> <rec> <name>a</name> <year>2002</year> </rec> <rec> <name tag="latest">z</name> <year>2005</year> </rec> <rec> <name>z</name> <year>2004</name> </rec> </root>
In other words, sort by <name> ascending and then by <year> descending while tagging the most recent of each name.
The sorting is easy, but tagging the most recent is proving difficult for me. I thought to use the preceding axis to test the preceding name and if it is different than the current name put in the tag attribute, but as I understand it, the precding axis applies to document order, not sort order. Is there some better way to do this?
Thanks, Stan Dyck
