However it seems (from reading the spec) that the following would be legal: <xsl:variable name="global" select="'text'"/> <xsl:template match="/"> <xsl:variable name="global" select="'newtext'"/> <xsl:variable name="globalnew"> <xsl:variable name="global" select="concat($global,'hi')"/> <xsl:value-of select="$global"/> </xsl:variable> <result><xsl:value-of select="$globalnew"/></result> </xsl:template> according to these rules of shadowing variables they have. I'm not sure if this would be legal (I'd check but I don't have the xslt 2.0 version of saxon on my machine anymore) <xsl:variable name="global" select="'text'"/> <p><xsl:variable name="global" select="concat('new',$global)"/><xsl:value-of select="$global"/></p> but I'm thinking that this might be? <xsl:variable name="global" select="'text'"/> <xsl:element name="p"><xsl:variable name="global" select="concat('new',$global)"/> )"/><xsl:value-of select="$global"/></xsl:element> taking somewhat further the ability in xsl 1.0 I never like of being able to declare a variable globally and locally. I tend just to name all my local variables loc{globalVariableName} if there is a relationship. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
