Variable update with new value

Question

Hallo,
How can i a variable (XML Publisher Syntax <?variable:name?>) one new value assign/update.
e.g.
initialize: <?variable:name?>[value]<?end variable?>
[loop]
new allocate:
<?variable:name?>[value]+1<?end variable?> -> doesn't work
[end loop]
I use the XML Publisher syntax because i use before function "instr".
who can me help. please. I'm to despair.
Thanks for help
Holger

As I understand you are looking for the Variable handling similar to X=X+1 , and you want to loop this from say 1 to 15.
- I think you just did not include the counter within the loop
- Also you are trying to loop on $YY, which first of all can not be accessed this way. You will have to use xdoxslt:get_variable($_XDOCTX, 'YY') . Secondly your loop should run against a group of data. It can be a variable like $YY but it should hold such a group of data.
so, assuming that your data is flat and grouped under ROW tag...
<?xdoxslt:set_variable($_XDOCTX, ’YY’, 1)?>
<?for-each:ROW[position()<16]?>HELLO
<?xdoxslt:set_variable($_XDOCTX, 'YY', xdoxslt:get_variable($_XDOCTX, 'YY') +1)?><?xdoxslt:get_variable($_XDOCTX, ’YY’)?>
<?if: (xdoxslt:get_variable($_XDOCTX, ’YY’))=15?>Yes Yes<?end if?>
<?end for-each?>
