Hello,
the separator has to be a single character as documented:
*
https://www.kamailio.org/wiki/cookbooks/5.5.x/transformations#sselect_index…
It does not support variables.
Looking at the code, it also does not support escaped characters,
probably this feature can be useful to introduce.
Cheers,
Daniel

Hello,
I am simply trying to parse a SDP body, read it line by line and save
the line into a variable for further processing. It seems when using a
newline \n as the delimiter it breaks down with errors. How should I
treat this issue and properly managed the newline as delimiter?
