Hello,

I need to get the value of first tgrp param in this string :
$var(x) = 
<sip:xxxxxxxxx;tgrp=0001000;[email protected]:5060;transport=UDP;user=phone;tgrp=237>

I'm trying $var(y) = $(var(x){param.value,tgrp});  but it's getting the last 
value of tgrp which is "237>".

Noting that first tgrp is not always in the second index , some other 
parameters can be added to the string.

How to get the value of first occurrence of  tgrp param ?

Regards,
Ali Taher
