UDP::payload replace

Anyone know if "replace" is supported in UDP::payload?   The documentation does not list it.     If not, does anyone know of a way to manipulate some data (generically) in UDP packets...

We're running 9.0.4.

 

 

Error appears when saving the rule through the GUI.

 

 

Here's the code:

 

 

 

 

 
 when CLIENT_DATA {  
 set payload [UDP::payload [UDP::payload length]]  
 set blank “\n”  
  
  Find the data to replace  
 regsub -all "Replace me\n" $payload $blank new_response  
  
  Replace the content if there was a match  
 if {$new_response != 0} {  
 UDP::payload replace 0 [UDP::payload length] $new_response  
 }  
 }

 

 

Result is wrong of arguments, line 10.
