RE: Re: "castable as" explanation
Thanks to both of you for your replies. Your confirmation that I understood the functioning of "castable as" led me to look elsewhere for the problem. It was a problem with substring indexes in the section of code triggered by the "true" evaluation of the "castable as" test. Although it occurred in proximity, the error was not functionally related to the "castable as" question. It's just that I was unfamiliar with "castable as", so my suspicion as to the locus of the problem fell there. -- Charles Knell cknell@xxxxxxxxxx - email -----Original Message----- From: Florent Georges <darkman_spam@xxxxxxxx> Sent: Mon, 28 Aug 2006 17:21:38 +0200 (CEST) To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: Re: "castable as" explanation cknell@xxxxxxxxxx wrote: > <xsl:variable name="is-date" select="if(DATE_PACKED_XSD > castable as xs:date) then '1' else('0')" /> Why not simply: <xsl:variable name="is-date" as="xs:boolean" select="DATE_PACKED_XSD castable as xs:date"/> > <xsl:choose> > <xsl:when test="$is-date = '1'"> > ... some processing here > </xsl:when> > <xsl:otherwise> > ... some different processing here > </xsl:otherwise> > </xsl:choose> > What I expected to happen was that when the stylesheet > processed a DATE_PACKED_XSD element that could not be cast > as a date ($is-date = 0), processing would pass to the > <xsl:otherwise> branch. > What did happen was this: > stylesheet.xslt:423: Fatal Error!
