Requesting multiple-level Muenchian examples or explan
Hi. My question pertains to the Muenchian trick to group XML records by unique values when the secondary key is optional (in other words it doesn't necessarily appear in each record). I have a large amount of xml I wish to sort and group on two keys (named keyword and keyword02). I have successfully managed to sort and group the data on keyword, which appears in every record. But I cannot get the data to then sort and group on keyword02 - which does not appear in every record. I understand that to add multiple levels with the Muenchian trick, you must concatenate the first and second keys to make a unique key, but when I try it the second level is simply not processed. Does the multi-level logic work when the second key is optional? I do know this would be easier to do in XLST 2.0, but that is not currently an option. Could anyone offer links or examples as to how to sort and group on 1 permanent key and 2 (or more) optional keys? I've already examined : http://www.jenitennison.com/xslt/grouping/muenchian.html (great articles by the way) http://www.biglist.com/lists/xsl-list/archives/ (many searches on grouping, Muenchian, sorting, ...) http://www.dpawson.co.uk/ (specifically: Sorting, Grouping, Sorting & Grouping) and http://www.netcrucible.com/xslt/msxml-faq.htm Thank you. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Rebecca Downey rdowney@xxxxxxxxxx Give us the money.
