This is regarding a counter issue.
Is there a possiblity that - every time i call a template - the template should increment the value by one.

For instance...if there is a counter variable x, and a counter template named xxxtemplate....every time i call the xxxtemplate, the counter variable should get incremented by 1.

[Which means every time i get to fetch this x variable...it should get incremented by one]

Kindly help, Thanx in advance.

As stated the answer is no, XSLT doesn't have mutable variables.
If you give an example of your problem then perhaps there will be another way of tackling it.

You can't update variables in a declarative language.

You can often achieve the effect your require using the position() function, or using an expression such as count(preceding-sibling::x).

In other cases you can use recursion: a template can call itself supplying a parameter such as

<xsl:with-param name="p" select="$p + 1"/>

Joe,
Thanx for your help in this regard. Lemme try to brief you out a lil more.

A certain block of elements have to get repeated
- which depends on certain set of attributes/rather conditions.

So when a condition is true - there is a need to execute this block which has a OrderNumber tag
that needs to get incremented with each loop execution.

Thatz the reason - for posting my previous message - of having a global variable which would get
incremented everytime, i call the templte that has the set of elements.

For instance if the input xml has
<test condition1='Y' condition2='Y' condition3='Y'condition4='N'condition5='Y'/>

I would be checking for each condition status.
For all the tru ones i need to call a template which would have

<OrderItem>
    <Action>Add</Action>
    <OrderNumber>1</OrderNumber>
    <OrderSubtype/>
    <ContactLastName/>
    <ContactTelephone/>
    <ContactTitle/>
    <ContactFirstName/>
</OrderItem>


Here the OrderNumber has to get incremented each time the template is called.
To make it very clear, if condition1 is Y, then the template is called once.
Hence, here - in the present stance - 4 conditions are Y...and hence there is a need to
call the above templete 4 times..The OrderNumber should abide by this too.

Hope you get my point.

thanx for your help.

You can do

<xsl:apply-templates select="@*[.='Y']"

<xsl:template match="@*">
   ....in here position() will give you the value you need ...

If you want the attributes processed in alphabetical order add an xsl:sort select="name()" as a child of xsl:apply-templates.

Thanx for the reply mike.
But how could we possibly get the position()?

thanx

position() is just an XPath function call, you can use it anywhere an XPath expression is allowed, e.g. in xsl:value-of.

ok mike. Lemme try that.
Thanx a lot for your timely help.
Appreciate it!

Mike/Joe,
One more issue here is that all the conditions that holds Y may not be required to execute the loop.
<test condition1='Y' condition2='Y' condition3='Y'condition4='N'condition5='Y'/>

Here if suppose i need only condition1/2/5 - only if these conditions hold Y, then i need to execute.
So i hope the template cant be a generic one and that we can't go for @*[.='Y']

Any comments on this?

thanx ,

Then you could use

apply-templates select="(@condition1, @condition2, @condition5)[.='Y']"

This would also give you a predictable order of processing the attributes.
