Global variables and changing within templates

["Pady Srinivasan" <pady@xxxxxxxxxxxxx>]

 

If I define a global variable, how can I pass it to a template, change it within the template, and be able to access the new value for the variable after the template processing is complete ?

 

<xsl:variable name="glovar" select="test"/>

 

<xsl:template match="/">

    <xsl:apply-templates select="TEST"/>

    <xsl:value-of select="$glovar"/>  <!--- Prints "newval" here  -->

</xsl:template>

 

<xsl:template match="TEST">

 

<!--- change glovar here -->

<xsl:variable name="glovar" select="newval"/>

 

</xsl:template>

 

 

 

 

Thanks
