Comparing cousins, at least that is what I think you'd call it. Apologies if this has been covered before. I didn't search through all 14,960 items in the archive but I did spend a couple of hours looking. I'm creating a table (on-line report). I want to insert a row in the HTML table that'll contain just the date when the date changes. My code (see below) is (I think) comparing all previous <mydate> elements with the current one. This is VERY SLOW. This database generated output is sorted by date so I really only need to compare the previous <mydate> with the current one. -and hopefully process the data a lot faster. If I understand correctly the siblings of <mydate> are <categoryid> and <eventid> so using preceding-sibling wouldn't help me. TIA, David Here's an XML Source fragment. <?xml version="1.0" encoding="UTF-8" ?> <root> <rowset count="1760"> <row ID="0"> <mydate>9/16/00</mydate> <categoryid>1</categoryid> <eventid>1</eventid> </row> <row ID="1"> <mydate>9/16/00</mydate> <categoryid>1</categoryid> <eventid>1</eventid> </row> <row ID="2"> <mydate>9/17/00</mydate> <categoryid>1</categoryid> <eventid>1</eventid> </row> <row ID="3"> <mydate>9/17/00</mydate> <categoryid>1</categoryid> <eventid>1</eventid> </row> </rowset> </root> <!-- This page was served in 213592 milliseconds by Cocoon 1.7.4 --> Here's some XSL to transform the above to HTML <?cocoon-process type="xsp"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xml:space="preserve" > <!-- I cut a lot of stuff out here --> <xsl:template match = "row"> <xsl:f test="smdate[not(.=preceding::smdate)]"> <!--- *** THIS LINE IS SLOW *** --> <tr> <td colspan="3" align="center"> <xsl:value-of select="smdate"/> </td> </tr> </xsl:if> <tr> <td><xsl:value-of select="categoryid"/></td> <td><xsl:value-of select="eventid"/></td> </tr> </xsl:template> XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
