Subject: Marking up a simple "and" condition in Boolean operations From: bryan.s.schnabel@xxxxxxxxxxxxxx Date: Wed, 19 Jul 2000 15:24:42 -0700 |
Hello experts, I am trying to perform what ought to be a simple Boolean operation, but I can't find the answer to this (maybe I'm not looking hard enough). How do I mark up a simple *and*? Input: <Graphic> <Image>t:\common\images\t848586.gif</Image> <Caption>NHL Hall of Fame</Caption> <NegNumber>556688998h8</NegNumber> </Graphic> DTD: <!ELEMENT Graphic ((Image | URL),Caption?,NegNumber?) > As you see. I might have an instance with Image or URL, and a NegNumber, or I might have and instance with Image or URL, but no NegNumber. I want to code for Image and NegNumber, or Image no NegNumber. My attempt: <xsl:template match="Graphic"> <xsl:choose> <xsl:when test="URL"> <Graphic URL ="{./URL}"> <xsl:apply-templates/> </Graphic> </xsl:when> <xsl:when test="Image"> <!-- I need an "and NegNumber" test here --> <Graphic Image ="{./Image}" NegNumber="{./NegNumber}"> <xsl:apply-templates/> </Graphic> </xsl:when> <xsl:when test="Image"> <Graphic Image ="{./Image}"> <xsl:apply-templates/> </Graphic> </xsl:when> <xsl:when test="Negnumber"> <Graphic NegNumber ="{./NegNumber}"> <xsl:apply-templates/> </Graphic> </xsl:when> <xsl:otherwise> <Graphic> <xsl:apply-templates/> </Graphic> </xsl:otherwise> </xsl:choose> </xsl:template> Thanks, Bryan Schnabel XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
