If you want to generate SVG barcodes, why don't you
use the barcode XSL form RenderX?

this code always writes

RE: incrementing variable

2002-11-05 Thread Phil Dickinson 



Xavier,

Each 
time you use the syntax xsl:variable name="x".../ you are declaring a 
new local variable, not modifying the existing one!

Since 
your output text occursbefore the new declaration, the global value is 
output displayed and this is always ten.

Try 
moving the fo:block section to after the declaration of the new 
variable.
