count of how many times a particular template is being called

[Tina Desai]

Can I get a count of how many times a particular
template is being called?
Im thinking of something like -
<xsl:variable name="globalVar" select"1" />
<xsl:template match="Node1">
<xsl:for-each select="$Values">
<xsl:call-template name="T1"/>
</xsl:for-each>
</xsl:template>
<xsl:template name="T1">
<xsl:if test="ValueIsValid">
<xsl:call-template name="T2"/>
</xsl:if>
</xsl:template>
<xsl:template match="T2">
Called for <xsl:value-of select="$globalVar" />
<!-- Increament the var??? -->
</xsl:template>
The final template creates the output.
I showed this for what I want. I know we cannot
reassign variables
in xsl. As I am iterating over $Values, that is a
variable, I am getting
undesired result by using xsl:number or position().
Can anyone give any hints?
Thanks

Tina, you can use position() function inside for-each element even if you iterate over a variable. This is probably the easiest way to do what you want. I do not think any trick with counting inside called template will work... Templates are functions, and functions in XSLT are free from side-effects, they do not keep state. You could accumulate this number in calling template and pass it as a parameter, using
<xsl:variable name="someVar" select="$someVar + 1"/>
trick, but here you aren't update a variable, you create a new one using old value. It won't work with if element, because of scope limitations.
To make position() function work looks more prominent.
