Subject: [xsl] alternating bg colour in nested data From: "Andrew Welch" <andrew@xxxxxxxxxxxxxxxxxxxxxxx> Date: Tue, 15 Jan 2002 17:51:21 -0000 |
Hi all, Im trying to get alternating table row background colours from nested xml. The xml is essentially nested groups. 1 contains 2,3 and 4. 2 contains 3 and 4 and so on. (This indicates that a group belongs to its parent and will be rendered expandable-collapsable-windows-explorer stylee) For example: <group1> <data1/> <data2/> <group2> <data1/> <data2/> </group2> <group2> <data1/> <data2/> <group3> <data1/> <data2/> </group3> <group3> <data1/> <data2/> <group4> <data1/> <data2/> </group4> </group3> </group2> </group1> I currently get alternating row colours using this kind of template for each group: <xsl:template match="group1"> <xsl:variable name="position" select="position()" /> <xsl:choose> <xsl:when test="$position mod 2 = 1"> <xsl:call-template name="row_even"/> </xsl:when> <xsl:otherwise> <xsl:call-template name="row_odd"/> </xsl:otherwise> </xsl:choose> <xsl:apply-templates select="group2"/> </xsl:template> Each template is virtually identical apart from the 'groupX' number. Also, occasionally two adjacent rows share the same colour (where group changes and last elem pos was even) Is there any way I can reduce the duplication in each template, and sort out the ocassional lapse in alternating colours? cheers andrew === XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
