Perhaps you could re-arrange the whole situation. Omar Lopez Ruiz sent this: <xsl:template matches="whatever"> <xsl:if test="something=true"> <some xsl tags and xsl:call templates> <xsl:variable name="foo" select="true"> </xsl:if> <xsl:if test="something=false"> <some other xsl tags> <xsl:variable name="foo" select="false"> </xsl:if> <xsl:value-of select="$foo"/> <!-- There's no foo var!!--> </xsl:template> It could be changed to: <xsl:template matches="whatever"> <xsl:variable name="foo" select="something"/> <xsl:choose> <xsl:when test="$foo"> <!-- Assumed to be faster than re-evaluating the "something" expression --> <some xsl tags and xsl:call templates> </xsl:when> <xsl:otherwise> <some other xsl tags> </xsl:otherwise> </xsl:choose> </xsl:template> By the way, notice that <xsl:if test="something=true"> is equivalent to <xsl:if test="something"> and if you're unsure of whether "something" is suitably boolean, you could say <xsl:if test="boolean(something)"> for your own peace of mind. .................David Marston XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
