[OpenSIPS-Users] I need some help in attr matching while forming the Branch .

[Sasmita Panda]

Ahhh , Ok .
Now it's very  complicated . When you said a loop that's looping in my mind
. Sorry for the bad joke .

In case , the number of elements in each Invite won't be fixed . So the
number of loops will vary from one Invite to another .
I was thinking of counting the number of elements first , then as the index
starts from 0 I will loop till *count-1* to fetch every element properly .

Example :
$var(count) = $(hdr(Call-Info){csv.count})    ## if the number is 3 then
loop will be for 3 times starting from 0 to 2

 $var(i) = 0;
    while($var(i) < $var(count) )
    {
        xlog("counter: $var(i)\n");
        $var(i) = $var(i) + 1;
    }

This was my initial thought . But while finding the count it gave me an
error . * $var(count) = $(hdr(Call-Info){csv.count})  Is this not in the
correct format ? *

*parse error in /usr/local/etc/opensips/opensips-p2p.cfg:267:26-55: unknown
script variable*

*As I have earlier mentioned my header will look like . *
*Call-Info: sales,en,level20,en (this can be anything but format will be
like this . )  . How do I count the number of values ?*

*2. As I am doing this matching to filter out contacts, where should I do
this ? If I am doing this while giving a call to the contacts , for the 1st
transaction it is doing the comparison , after that for the next branch it
processes the call without matching . Which is not right . For every
contact this comparison should loop *

*Thanks & Regards*
