here's a basic question (which I couldn't find any info neither on the net nor looking into this mailing list archive).

It is a very FAQ.

The (programming) idea is to get a global variable and to modify its value,

The side-effect-free functional programming idea is to bind values to variables within their scope thus preventing variables from being modified.

XSLT is side-effect-free, thus classical programming techniques do not apply.

To have the processor count constructs you need from your source node tree, use either <xsl:number> or the count() function.

I hope this helps.
