Subject: Positional predicates in pattern matching From: Kevin Jones <kjones@xxxxxxxxxxx> Date: Fri, 2 Jul 2004 16:34:35 +0100 |
I have seen some behaviour in Saxon 6.5.2 and Xalan that I can't really explain by reading the standard. I have probably just missed something but would appreciate some second opinions. If you execute, <xsl:template match="/"> <xsl:variable name="foo" select="a/b[position()>1]"/> <top> <xsl:apply-templates select="$foo" mode="one"/> <xsl:apply-templates select="$foo" mode="two"/> </top> </xsl:template> <xsl:template match="b[1]" mode="one">P1</xsl:template> <xsl:template match="b[2]" mode="one">P2</xsl:template> <xsl:template match="b[3]" mode="one">P3</xsl:template> <xsl:template match="b[true()][1]" mode="two">R1</xsl:template> <xsl:template match="b[true()][2]" mode="two">R2</xsl:template> <xsl:template match="b[true()][3]" mode="two">R3</xsl:template> Against, <a> <b/> <b/> <b/> </a> The result is P2P3R2R3. I was expecting either P2P3R1R2 or perhaps even P2P3R1R1. It is obvious why you get P2P3 but that is only true for the first predicate of a StepPattern. In the second set of templates I would expect the positions should be 1 & 2 or perhaps even just 1 twice since pattern matching is defined as being a processes applied to individual nodes. Thanks, Kev.
