Get multiple fields from string

You could use getfield for each field, but I think scan would be more efficient. Here are a few examples:

 
 when RULE_INIT { 
  
    set ip 11.22.33.44 
    scan $ip {%d.%d.%d.%d} a b c d 
    log local0. "$a, $b, $c, $d" 
  
    set str "e f g h" 
    scan $str {%s %s %s %s} a b c d 
    log local0. "$a, $b, $c, $d" 
  
    set str "i 2 k 4" 
    scan $str {%s %s %s %s} a b c d 
    log local0. "$a, $b, $c, $d" 
 } 
 

And the log output:

Rule : 11, 22, 33, 44

Rule : e, f, g, h

Rule : i, 2, k, 4
