I have literally nothing as far as this function. This is a chat bot for a hopelessly obscure TTY-based chat system. Right now, it logs in, idles, and responds to specific commands as part of a loop. So far, I haven't had to make any of those responses depend on a particular part of the command. This function will be the instruction to move the bot to another room. If this were IRC, it'd be so much easier.
Essentially, the bot will see as text in the room "kimiko, go to " (the bot's account name is kimiko), and the word immediately following the space after 'to' will be the room name. I want the script to use "kimiko, go to " as the trigger (expect "kimiko, go to ") and the action to be to capture the following word.

This is part of the main loop. I left some of the functions in so you can see how it operates. The changing room thing basically has me scratching my head completely. I know how to make it look for the trigger phrase. I don't know how to initiate capturing the next word after the trigger phrase.

Code:

while {$Exit != 1 } {
# Temporary simulated commands/responses
expect {
# Greeting, response
    "hai kimiko"    {
        send "\r"
        send "o hai\r"
    }
# Change rooms
    "kimiko, go to"    {
        #Capture the word following 'kimiko, go to ' and store in GoRoom
        send "g" # Initiates room change
        send "$GoRoom\r" #Dumps GoRoom variable into change room command
     }
# Approval of all 'kick' actions against user 'magizian'
    "needs approval to kick magizian"    {
        send "k"
        send "approve\r"
    }
# Exit commandÍ
    "kimiko, you may go now"    {
# Sets Exit variable to 1 to cause loop to exit
        set Exit "1"
        send "\r"
        send "bai\r"
    }
}

# Close brace for end of 'while' loop
}
