You don't need substring() to implement index-of(). To expand DC's response, here it is: <xsl:function name="eg:index-of" as="xs:integer"> <xsl:param name="a1" as="xs:string?"/> <xsl:param name="a2" as="xs:string?"/> <xsl:sequence select="string-length(substring-before($a1, $a2)"/> </xsl:function> and perhaps: <xsl:function name="eg:index-of" as="xs:integer"> <xsl:param name="a1" as="xs:string?"/> <xsl:param name="a2" as="xs:string?"/> <xsl:param name="collation" as="xs:string"/> <xsl:sequence select="string-length(substring-before($a1, $a2, $collation)"/> </xsl:function> Michael Kay http://www.saxonica.com/
