RE: [xsl] Incrementing a Variable

["Tim Watts" <timw@xxxxxxx>]

Jon,

You can't actually increment a variable.  Once it is declared it must stay
the same.

The effect you want can be achieved through the use of recursive templates -
that is that the template calles itself again passing a new value
incremented by one.

A good example of recursion if found at
http://www.angelfire.com/tx4/cus/shapes/bottles.html
where the XSLT recurses through the 99 bottles of beer song.

It really helped me to understand the concept.

Cheers,
Tim Watts :)

It was my understanding that you can increment a variable in xsl by 1, say
during each pass of a for loop. Is this true and if not, what's the best way
to achieve this?
