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

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>
