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?

Block extracted from .cfg

 

sdp_get("$avp(sdp)");

$avp(lines) = $(avp(sdp){line.count});

$var(delimeter) = "\n";

 

$var(i) = 0;

while($var(i) < $avp(lines)) {

 

        # This works

        xlog("L_INFO", "==> Position $var(i): $(avp(sdp){s.select,$var(i),\n}) \n");

 

        # This fails

        $var(l1) = $(avp(sdp){s.select,$var(i),$var(delimeter)});

 

        # This fails

        $var(l2) = $(avp(sdp){s.select,$var(i),\n});

 

        # This fails

        $var(l3) = $(avp(sdp){s.select,$var(i),\\n});

 

        # Supposed to do something funny with the $var(line) here

 

        $var(i) = $var(i) + 1;

 

}
