NGINX Rewrite rules with arguments

Question

I'm stuck with an NGINX rewrite rule and hope you can help me out or point into the right direction. My problem looks like this:

I want to rewrite an URL if a specific argument appears. For example argument=1 like this: www.old_domain.com?argument=1&id=1&l=dfsdgsh

If this argument flag appears, redirect it to another domain, but keep the part after argument=1. For example redirect to: www.new_domain.com?id=1&l=dfsdgsh

I understand how to redirect the whole old domain to a new domain, but I'm having trouble to understand how to identify the argument flag and then how to take the last part to the new domain.

Cheers, Szop

Example:

if ( $args ~ argument=([0-9]+)&id=1&l=([\w]+) ) {
    set $arg  $1;
    set $l $2;
 }

if ( $arg = 1) {
   rewrite (.*)  http://domain1/?id=$arg&l=$l?;
}

if ( $arg = 2) {
       rewrite (.*)  http://domain2/?id=$arg&l=$l?;
}
