I use this structure of data ;

typedef struct AR\_zone\_t {  
int etat;  
int duree;  
int sortie;  
int indice\_valide;  
};

struct AR\_zone\_t AR\_zones[8];

It works with Dynamic c 9.62 but it seems that it does not work with 10.72D because I still have problems reading variables in a xml files

How to write the structure?

Thanck you for the answer.

How are you indexing that array in your RabbitWeb/ZHTML files? You should be using index 0 to 7. Maybe you should email me with the ZHTML file you’re using, and what the Rabbit’s generated output looks like so I can help you troubleshoot.

The solution is :

With this structure

Ihave declared the variable web as in my program with Dynamic C 9.62

#web AR\_zones[@].etat groups=user(rw)  
#web AR\_zones[@].duree ((0 \< $AR\_zones[@].duree) && ($AR\_zones[@].duree \<= 20)) groups=user(rw)

This syntax don’t work with Dynamic 10.72D

You have to declare the variables like this.

#web AR\_zones groups=user(rw)
