Re: help defining regular expressions

You cannot use && inside a regex. But you can use it outside:

if( $packet !~ m/sip/ && $packet !~ m/sdp/ ) {
     print "packet is RTP\n";
}
elsif( $packet =~ m/sip/ ) {
    if( $packet =~ m/sdp/ ) {
         print "packet is sdp\n";
    }
    else {
         print "packet is sip!\n";
    }
}

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
