Subject: Re: [xsl] accessing node by position From: David Carlisle <davidc@xxxxxxxxx> Date: Wed, 19 May 2004 11:14:56 +0100 |
I need to access an xml value by it's position. can this be done (or is there a better way to do it) to access the 3rd foo element just do foo[3] <xsl:value-of select="../../../columns/column(position())/type"/> You need square brackets not round, and you want to evaluate position() in the current node list _before_ you start this xpath as it's the current position that you want, so <xsl:variable name="x" select="position()"/> <xsl:value-of select="../../../columns/column[$x]/type"/> Of course for $x to have teh right value you need to make sure that your current node list only has cell nodes, if you just do an <xsl:apply-templates/> rather than <xsl:apply-templates select="cell"/> on the row element then your current node list will include white space text nodes and so the position of teh cell elements will be 2,4,6,... not 1,2,3,...
