RE: [xsl] xsl:variable

This is a very frequently-asked question. In short, you can't re-assign the value of a variable once it has been declared. Not no way, not no how, so don't waste any more time looking for a way to do it.

As to scope, a variable goes out of scope when the processor exits template in which it was declared. So your answer is to declare the variable at the top level, inside the <xsl:stylesheet> element.

These matters are usually resolved by passing values into a recursive template, picking up its value via <xsl:param>, defining a new variable inside the template using the value of the parameter, and passing it along to the next iteration of the template via <xsl:with-param>.

Hi

        Hopefully I'm just missing something silly here.  I need to 
declare a variable that will be used globally and possibly modify if a 
condition occurs. Yet I cannot discern the syntax to do so , any attempt 
seems to re-declare the variable.



The intent here is to increment the value pages if the condition is true. 
If I declare a new variable within the If to hold the value it will go out 
of scope which doesn't help me.

Ie.
Thanks in advance for any ideas.

<xsl:variable name="pages" select="( $totalitems - $leftover ) div 
$pagesize "/>
<xsl:if test="leftover > 0 ">
        <xsl:variable name="$pages" select="$pages  =$pages +1"/>
</xsl:if>
