Subject: RE: [xsl] Can grouping here the solution ? From: Robby Pelssers <Robby.Pelssers@xxxxxxx> Date: Mon, 21 Nov 2011 18:41:58 +0100 |
You can do something like <xsl:for-each group select="display-articles/section/entry" group-by="concat(substring(datum/text(), 1,7), '/', page/text())"> <!-- this way you group on unique combinations of e.g. strings like '2005-02/1' --> </xsl:for-each> Robby -----Original Message----- From: Roelof Wobben [mailto:rwobben@xxxxxxxxxxx] Sent: Monday, November 21, 2011 6:33 PM To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: RE: [xsl] Can grouping here the solution ? what I try to achieve is this. As you can see I have some articles for testing purposes. I like to display them per month and per page where I can decide how many articles are displayed. This depends on the month and the page the user is on my website. I hope it's clear what I want.
