Subject: Re: [xsl] Just the first 'x' elements within a for-each From: Simon.Fairey@xxxxxx Date: Tue, 18 Mar 2003 14:15:05 +0000 |
Jeni, Ah I see, I'm beginning to get the picture, the second version worked but the first didn't and after a good look I realised it's due to the nature of the data and the fact there is only one properties element per story element. What I wanted (as the second example shows) is the properties element of the first 2 story elements rather than just the first 2 properties elements. Many thanks Si Jeni Tennison <jeni@xxxxxxxxxxxxxxxx> 18/03/2003 14:01 Please respond to Jeni Tennison To: Simon.Fairey@xxxxxx cc: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: Re: [xsl] Just the first 'x' elements within a for-each Hi Si, > The following displays all the headlines rather than just the first 2: > > <xsl:stylesheet version="1.0" > xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> > <xsl:output method="html"/> > <xsl:template match="/"> > <xsl:for-each select="/package/stories/story/properties[position() <= 2]"> > <!-- We only want the first 2 headline --> > <br/> > <xsl:value-of select="headline"/> > </xsl:for-each> > </xsl:template> > </xsl:stylesheet> Ah, right -- the position that's used in the predicate here applies to the position of the <properties> element within its <story> parent, rather than the position of the <properties> element amongst all the <properties> elements (within <story> elements, within...) in the document. You just need to add some brackets: <xsl:for-each select="(/package/stories/story/properties)[position() <= 2]"> ... </xsl:for-each> this will collect up the <properties> elements into a node set and the position of a particular <properties> element will be judged based on its position, in document order, amongst the other nodes in that node set. Or (depending on the structure of the XML) you might be able to move the predicate so that it's getting the position of the right thing. For example, perhaps you want the <properties> children of the first two <story> elements: <xsl:for-each select="/package/stories/story[position() <= 2]/properties"> ... </xsl:for-each> Cheers, Jeni --- Jeni Tennison http://www.jenitennison.com/ ********************************************************************************** This email may contain confidential material.
