Subject: [xsl] Key and/or grouping questions. From: "Edward L. Knoll" <ed.knoll@xxxxxxxxxxxxxx> Date: Wed, 04 Dec 2002 13:46:53 -0700 |
I have a set of style sheets which have a sever performance problem. Distilled (hopefully not diluted past usefulness), I am processing a large set of sibling elements a few elements at a time. I believe the problem is with the following statement (which I've changed/condensed the expression of): <xsl:for-each select="/elements[ (position() >= $Start) and (position() <= $End) ]"> ... </xsl:for-each> I was referred to a FAQ on grouping and this led me to attempt to setup some kind of solution utilizing keys. Unfortunately, the XSL reference I have has no information on <xsl:key> and my favorite FAQ has a list of topics under keys with no corresponding content. Anyway, my XSL processor (Xalan) doesn't like my key definition. Is the "use" parameter limited from being a numerical expressions? <xsl:key name="PageKey" match="/gnsl:Results/gnsl:Table/gnsl:Row" use="((position() - 1) / $RowsPerPage) + 1)" /> Thanks, Ed Knoll -- Edward L.
