Hi Rudolf, > I'm having problem with position(). > I need position of node which is not tested now, eg. > <data> > <value attr="first">...</value> > <value attr="second">...</value> > </data> > > <!--xsl:value-of select="position(data/value[@attr = 'second'])"/--> > of course this cannot run :-)) position() returns always the position of the current node within the context node list. There's nothing like a "global position". For example: if you have <xsl:template match="value[@attr='second']"> <xsl:value-of select="position()" /> </xsl:template> you might think to get always the same value. No, that's not the case. position depends, as I said, on the context node list. I.e. <xsl:apply-templates select="//*" /> <xsl:apply-templates select="/data/value" /> <xsl:apply-templates select="/data/value[@attr='second']" /> gives three different numbers. So, what do you mean by "position"? The position of the value element among its value siblings? Then just count the preceding siblings and add 1: <xsl:value-of select="count(data/value[@attr='second']/preceding-sibling::value)+1" /> Or alternatively you could use the power of <xsl:number />: <xsl:for-each select="data/value[@attr='second']"> <!-- this only changes the context node --> <xsl:number /> </xsl:for-each> Cheers, Oliver /-------------------------------------------------------------------\ | ob|do Dipl.Inf.
