[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] strong typed variable with restriction ?
 I have a xsl:function which : - must return a element() - has a string param "foobar". I typed $foobar as xs:string but I'd like to restrict the possible values to "foo" or "bar". I know it's possible to define such a constrain in a xsd schema, but is there a way to do that in xpath2 ? This typing is important because the returned element() is selected from a xsl:choose on $foobar value (with no otherwise) : My code looks like : <xsl:function name="igs:get-css-rule" as="element()"> <xsl:param name="foobar" as="xs:string"/> <!--(foo|bar)--> <xsl:choose> <xsl:when test="$foobar='foo'"> <xsl:sequence select="igs:get-my-foo-item()"/> </xsl:when> <xsl:when test="$css='bar'"> <xsl:sequence select="igs:get-my-bar-item()"/> </xsl:when> </xsl:choose> </xsl:function> And I get such a parsing error on my xslt : XTTE0570: Conditional expression: If none of the conditions is satisfied, an empty sequence will be returned, but this is not allowed [...] Should I import my own schema to my xsl to define my special type derived from xs:string ? Thanks for your advices, Matthieu.
