You need to do the parsing/extraction natively within the expect script. The solutions given so far require a spawning of 'awk' which I'm not sure if expect allows.
I'm no expect guru, but maybe other will help.

Full Script
Code:
#!/usr/bin/expect

set timeout 20

set ms [lindex $argv 0]

log_user 1

#Testnode

spawn ssh "testuser\@*************"
expect -re "testuser@****************'s password:"
send "************\r";
expect -re "Testnode>"
log_file "log.txt" ;
send "show ******************* $ms\r"
expect -re "Indicator"
log_file;
MYIP=$(awk '/TEST IP/ && !/n\/a/ {print $NF;exit}' file)
send "show *********************************** $MYIP"

Study tk and tcl tutorials online, as expect is made from, and scripted with, these languages.

Alternatively, I have written expect-like scripts that mostly ran in the parentheses piped to stdin, examining the log file where stdout and stderr are being written. This rescues me from learning another script langage. It does have minor problems getting control of /dev/tty if that is where passwords and such are read from. For instance, a primitive remote smtp/esmtp email client from telnet:
Code:
$ (
  >>my_mailer_log
 
  <script that examines log file my_mailer_log for progress and generates input>
 ) | telnet mailhost 25 > my_mailer_log 2>&1

Hi Guys,
Just to follow up really, I managed to complete what i needed by using a perl script which then called an expect script in order to login to the relivant elements and run the commands required.

Thanks to everyone who helped.
