Subject: Re: [xsl] Conditionally assigning value to a variable from a parameter if the parameter is a non-zero number (only numbers, no alphabets or other chars) From: Wendell Piez <wapiez@xxxxxxxxxxxxxxxx> Date: Thu, 30 Oct 2003 14:14:26 -0500 |
<xsl:variable name="ImageWidthRender"> <xsl:choose> <xsl:when test="number($ImageWidth)"> <xsl:value-of select="$ImageWidth"/> </xsl:when> <xsl:otherwise> <xsl:value-of select="$SBWidth"/> </xsl:otherwise> </xsl:choose> </xsl:variable>
Cheers, Wendell
How can I conditionally define the value for a variable?
I want to check if the incoming parameter ImageWidth is a non-zero number. If it is a non-zero numeric string (i.e. it is a non-zero number) then I want to assign its value to the variable.
If not then I want to assign another parameters value to the variable
Is there a better way to do that checking/ assignment?
Is the following valid??
<xsl:variable name="$ImageWidthRender"> <xsl:choose> <xsl:when test="$ImageWidth='Nothing'"><xsl:value-of select="$SBWidth"></xsl:value-of></xsl:when> </xsl:choose> <xsl:choose> <xsl:when test="$ImageWidth='0'"><xsl:value-of select="$SBWidth"></xsl:value-of></xsl:when> </xsl:choose> <xsl:choose> <xsl:when test="$ImageWidth=''"><xsl:value-of select="$SBWidth"></xsl:value-of></xsl:when> </xsl:choose> <xsl:choose> <xsl:when test="$ImageWidth=' '"><xsl:value-of select="$SBWidth"></xsl:value-of></xsl:when> </xsl:choose> <xsl:choose> <xsl:when test="string-length(translate($ImageWidth,'0123456789','')) = 0 and $ImageWidth != 0"><xsl:value-of select="$ImageWidth"></xsl:value-of></xsl:when> </xsl:choose>
</xsl:variable>
