Subject: RE: [xsl] select="if (subelement) then subelement else 'string'" From: "Pawson, David" <David.Pawson@xxxxxxxxxxx> Date: Thu, 3 Feb 2005 10:27:21 -0000 |
-----Original Message----- From: Michael Kay I often write select="(pages, 0)[1]" Clarification please, generate a sequence which has either one or two items; then take the first? Sequence is either [123, 0] or [0] which gives what the OP wanted? Is that right (DC terminological corrections notwithstanding). TIA, DaveP. > Is there a simpler or more efficient way to provide '0' when the pages > subelement isn't present (or 0, since the template outputs it via > xsl:value-of)? -- DISCLAIMER: NOTICE: The information contained in this email and any attachments is confidential and may be privileged.
