Function application is not so dynamic in XPath/FXPath. You cannot convert the $expr string into an expression which gets evaluated. You would have to test for the string value of $expr value as in <xsl:template match="*" mode="com:eval"> <xsl:choose> <xsl:when test="$expr = '.'"> <xsl:value-of select="."/> </xsl:when> <xsl:when test="starts-with ($expr, 'contains (.,')"> <xsl:if test='contains (., substring-before (substring-after ($expr, "'"), "'"))'>true</xsl:if> </xsl:when> ... </xsl:template> This isn't particulary dynamic or scalable, but I believe this is the intended use of $expr in com:eval.
