Subject: [xsl] grouping question From: Patrick Moore <patrickm@xxxxxxxxxxx> Date: Thu, 12 Apr 2001 17:44:59 -0700 |
Hi there -- I have looked through the email about grouping withput finding this question being answered. I am using Xalan sql extension to generate the data that will be processed by the xsl stylesheet. Because it is a database query I have constructed the query so the results are sorted based on the element that I wish to group by. Because this extension lets me look at only one row at a time, and I cannot go back, the Mueschean method is not possible. (Or at least not prefered). I was wondering if anyone had some thoughts on a way I can take advantage of the ordering that SQL can do to come up with a simpler method. Some sample data: <rowset> <row><album>1</album><track_id>1</track_id><artist>Rush</artist></row> <row><album>1</album><track_id>2</track_id><artist>Rush</artist></row> <row><album>2</album><track_id>1</track_id><artist>Rush</artist></row> <row><album>2</album><track_id>2</track_id><artist>Rush</artist></row> </rowset> As soon as I see the "Album 2" I know that there are no more <album>1</album>'s Can I take advantage of this in any manner? My preliminary conclusion is no... but I am new enough to xsl to wonder if this is indeed the case. -Patrick Moore XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
