 Is there an easy way to determine whether 2 sequences of xs:string+ intersect. I am not able to use: $seq1 intersect $seq2 because they need to be nodes. An example with my lame(?) solution at the bottom: I have a sequence of 'role' elements, e.g. <dbo.ROLE USER_ID="19955" ROLE="CAEMP"/> <dbo.ROLE USER_ID="19955" ROLE="INCPL"/> <dbo.ROLE USER_ID="19955" ROLE="MNGR"/> <dbo.ROLE USER_ID="19955" ROLE="NewHire"/> <dbo.ROLE USER_ID="19955" ROLE="NONHIEMP"/> <dbo.ROLE USER_ID="19955" ROLE="VEHALLW"/> which is converted to a sequence of xs:string by: <xsl:with-param name="roles" as="xs:string+" select="for $r in $roles return string($r/@ROLE)" tunnel="yes"/> and I have an attribute that identifies role restrictions in another document context, e.g. <task roleRestrictions="CAEMP VEHALLW"/> which is converted to a sequence by: <xsl:variable name="restrictions" select="tokenize(@roleRestrictions, ' ')" as="xs:string+"/> So, what I am doing to get a value to show as true or false in a table cell is: <xsl:sequence select="not(empty(index-of(f:has-role($roles, $restrictions), true())))"/> .... <xsl:function name="f:has-role" as="xs:boolean+">
<xsl:param name="roles" as="xs:string+"/>
<xsl:param name="restrictions" as="xs:string+"/>
<xsl:sequence select="for $r in $restrictions return
if (index-of($roles, $r)) then true() else false()"/>
</xsl:function>Is there a better way? thanks, -Rob
