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)

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

Abhishek,

Your xsl:choose is missing an xsl:otherwise clause, and the name in the 
assignment is wrong (has a '$' in it); otherwise it's okay.

But wouldn't it be much neater to say:

<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
