Re-assigning a variable's value

Hi there,

I am very new to XSL. I wanted to do the following:

Assign a variable named "Total_Amount" in the global scope.

Then I loop through each child nodes using

<xsl:for-each select="RESULTSET/ROW">

and add the node value of "Amount" to the global "Total_Amount" variable and finally display it as Grand Total at the end.

<xsl:variable name="Total_Amount"><xsl:value-of select="$Total_Amount + $Amount"/></xsl:variable>

But the global variable is not being modified. It seems that it creates a local variable with the same name of the global variable.

Also it seems that a variable within the for loop is not global even within each iteration of the loop.

I have no idea how to work this around.
Please shed some lights on my issue.

Thanks a lot.

What version of XSLT are you using ?
To the best of my knowledge, re-assigning variables is not an option until XSLT 1.1.

variables once declared using <xsl:variable> cannot be re-assigned.
You can however achieve what you want by using xsl:call-template by passing the values recursively.

Hi kahaji,

Thanks for your reply. Can you please give an example of how to use xsl:call-template and pass the value recursively to achieve what I wanted.

Thanks a lot.

Here's an introduction to recursive programming with XSL: http://www-106.ibm.com/developerwor...ecur/?n-x-10242

Thanks for directing me.

I will go through it .

Hi

There is another example of recursion with XSLT
