I am reading XSLT Programmer's Reference by Michael Kay and he has a discussion on the topic "Programming without Assignment Statements" The following example is offered (p551) to demonstrate the paradigm shift from procedural programming to functional programming int x; if (zeroBased) { x=0; } else { x=1; } <xsl:variable name="x"> <xsl:choose> <xsl:when test="$zeroBased"> 0 </xsl:when> <xsl:otherwise> 1 </xsl:otherwise> </xsl:choose> </xsl:variable> How would the example above be extended to XSLT using an if statement with more complex then and else bodies such as below? int x,y; if (zeroBased) { x=0; y=3.14159; } else { x=1; y=2.71828; } The following seems verbose, inefficient and impractical: <xsl:variable name="x"> <xsl:choose> <xsl:when test="$zeroBased"> 0 </xsl:when> <xsl:otherwise> 1 </xsl:otherwise> </xsl:choose> </xsl:variable> <xsl:variable name="y"> <xsl:choose> <xsl:when test="$zeroBased"> 3.14159 </xsl:when> <xsl:otherwise> 2.71828 </xsl:otherwise> </xsl:choose> </xsl:variable> Please cc a response direct to me as I am on digest. Thanks in advance. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
