RE: [xsl] [XSL] Calculating Length of String Variables

[Alice Ju-Hsuan Wei <ajwei@xxxxxxxxxxx>]

Thanks to Michael and Jing. This part is now working and prints out the 
"value of the string length" accurately.

However, when I tried to use the node with the result of "123456," it 
prints out the "string-length" as a 6 preperly. But when I try to run a 
"test" of action according to this result, it does not perform any of 
the actionsth as in <xsl:when test="string-length($image_src_ ='6'">, 
but performs the actions as in 
<xsl:when-test="string-length($image_src)='4' or '5'"> as shown below:

<xsl:when test="string-length($image_src) = '4' or '5'">
               <img>
                   <xsl:attribute name="src">images/<xsl:value-of 
select="./@url"/>.gif</xsl:attribute>
                   <xsl:attribute name="alt"> Picture No. 
<xsl:value-of select="./@url"/>
                   </xsl:attribute>
             </img>
           </xsl:when>
<xsl:when test="string-length($image_src) = '6' ">
               <img>
                   <xsl:attribute name="src">images/<xsl:value-of 
select="substring($image_src,1,4)"
                       />.gif</xsl:attribute>
                   <xsl:attribute name="alt"> Picture No.  
<xsl:value-of select="substring($src,1,4)"/>
                   </xsl:attribute>
              </img>
           </xsl:when>

 Does anyone know if there is something I should have done that I have not?

Thank again.
